The President of India is elected by a proportional representation system through single transferable vote. This implies that

1. The Union Executive and the President's Role (basic)

Welcome to your first step in understanding how India chooses its highest constitutional authority! To understand the Presidential election, we must first understand who the President is within our system of government. In India, the Union Executive consists of the President, the Vice-President, the Prime Minister, the Council of Ministers, and the Attorney General of India. Unlike the United States, where the President holds supreme executive power, India adopted a Parliamentary form of government. This means that while all executive actions of the Government of India are formally taken in the President's name, the President is a nominal (titular) executive, whereas the real executive power lies with the Council of Ministers headed by the Prime Minister Indian Polity, M. Laxmikanth, Chapter 18, p.199.

The constitutional foundation of this role is found in Article 53, which states that the executive power of the Union is vested in the President and shall be exercised by him either directly or through officers subordinate to him. However, this power is not absolute. Under Article 74, the President is bound to exercise these functions with the 'aid and advice' of the Council of Ministers Indian Polity, M. Laxmikanth, Chapter 18, p.200. This distinction is crucial: the President represents the nation but does not rule the nation. They are the Head of the State, while the Prime Minister is the Head of the Government.

To help you visualize the difference between our system and the one used in the US, look at this comparison:

Feature	Indian President (Parliamentary)	American President (Presidential)
Nature of Power	Nominal/Constitutional Head (De Jure)	Real Executive Head (De Facto)
Responsibility	Acts on the advice of the Cabinet	Not bound by a Cabinet; holds independent power
Symbolism	Symbol of unity and integrity of the nation	Head of both the State and the Administration

2. The Electoral College (Article 54) (basic)

In India, the President is not elected directly by the people but through an indirect election. This is conducted by a specific body known as the Electoral College, as mandated by Article 54 of the Constitution. The core philosophy behind this system is to ensure that the President represents the entire nation—both the Union and the States—equally. According to Laxmikanth, M. Indian Polity, Chapter 18: President, p.186, the Electoral College consists of:

• Elected members of both Houses of Parliament (Lok Sabha and Rajya Sabha).
• Elected members of the Legislative Assemblies (Vidhan Sabhas) of all States.
• Elected members of the Legislative Assemblies of the Union Territories of Delhi and Puducherry.

It is vital to note that nominated members of any house and members of Legislative Councils (Vidhan Parishads) do not participate in this process to maintain the democratic purity of the office.

To ensure uniformity among the states and parity between the Union and the States, the votes are not counted as 'one person, one vote.' Instead, each vote is assigned a value based on the population. For an MLA, the vote value is calculated by dividing the state's population (based on the 1971 census) by the total number of elected members in that Assembly, further divided by 1000. This is why an MLA from a populous state like Uttar Pradesh has a much higher vote value (208) than an MLA from Sikkim (7).

At the national level, the value of an MP's vote is uniform. It is derived by taking the total value of all MLA votes from across the country and dividing it by the total number of elected members of Parliament. This ensures that the collective weight of all the States together exactly equals the collective weight of the Union (Parliament). As noted in D. D. Basu, Introduction to the Constitution of India, The Union Executive, p.237, this complex weighting system is designed to prevent the President from being a mere 'nominee' of the majority party in Parliament, making them a true representative of the federal structure.

3. Proportional Representation vs FPTP (intermediate)

To understand how the President is elected, we must first distinguish between the two primary ways of translating votes into winners. Most of us are familiar with the First-Past-The-Post (FPTP) system used in Lok Sabha and Assembly elections. In FPTP, the candidate with the highest number of votes wins, even if they don't have more than 50% of the total votes. While simple, this system can lead to 'territorial representation' where minorities or smaller political groups remain unrepresented Laxmikanth, M. Indian Polity, Parliament, p.225. In contrast, Proportional Representation (PR) aims to ensure that every section of the population gets its due share of representation in proportion to its numbers.

India adopts a specific variant of PR known as the Single Transferable Vote (STV) system for the election of the President, Vice-President, and members of the Rajya Sabha Laxmikanth, M. Indian Polity, Parliament, p.225. Unlike FPTP, where a voter marks a single choice, in the STV system, the voter (in this case, an MLA or MP) ranks candidates in order of preference (1st, 2nd, 3rd, etc.). To be declared the winner, a candidate cannot simply have more votes than others; they must secure a specific minimum quota of votes NCERT Class XI, Indian Constitution at Work, Election and Representation, p.60. This ensures the winner has a broad base of support rather than just being the 'least disliked' candidate.

The reason India chooses PR over FPTP for the Presidency is deeply philosophical. The President is the head of the Indian State and represents the entire Union. Using FPTP could allow a candidate supported only by a large single party to win easily. PR ensures that the President is elected by a clear majority and reflects a consensus across different states and political parties, maintaining the federal balance of the country.

Feature	First-Past-The-Post (FPTP)	Proportional Representation (STV)
Winning Criteria	Plurality (Highest votes wins)	Quota (Absolute majority/threshold)
Voter Choice	Single choice for one candidate	Preferences/Ranking of candidates
Representation	May exclude smaller groups	Ensures due representation to all sections
Usage in India	Lok Sabha, State Assemblies	President, Rajya Sabha, State Councils

4. Comparison: President vs Vice-President Elections (intermediate)

Hello! Now that we’ve explored how the President is elected, it is vital to contrast this with the election of the Vice-President. While both offices represent the pinnacle of our executive, their election processes are designed differently to reflect their specific constitutional roles. The most fundamental similarity is the manner of election: both are elected indirectly through a system of proportional representation by means of a single transferable vote (PR-STV) with a secret ballot Laxmikanth, M. Indian Polity, Vice President, p.203. However, the composition of the 'voters' (the Electoral College) is where the paths diverge significantly.

The Electoral College for the Vice-President differs from the President’s in two major ways. First, the Vice-President’s election includes both elected and nominated members of Parliament, whereas nominated members are strictly excluded from the Presidential election. Second, State Legislative Assemblies have no role in electing the Vice-President; it is purely a Parliamentary affair Laxmikanth, M. Indian Polity, Vice-President, p.203. This is because the Vice-President primarily functions as the Chairman of the Rajya Sabha, and only rarely acts as the President. Therefore, it wasn't deemed necessary to involve the State legislatures in their appointment.

Beyond who votes, there are also differences in eligibility and the nomination process. To be a President, one must be qualified for election as a member of the Lok Sabha; for a Vice-President, one must be qualified for the Rajya Sabha D. D. Basu, Introduction to the Constitution of India, The Union Executive, p.208. Furthermore, to prevent 'frivolous' candidates, the law requires a specific number of supporters from the electoral college. For the President, a candidate needs 50 proposers and 50 seconders, while the Vice-President needs 20 proposers and 20 seconders Laxmikanth, M. Indian Polity, Electoral Reforms, p.584.

Feature	Presidential Election	Vice-Presidential Election
Electoral College	Only Elected members of Parliament & State Assemblies.	Both Elected & Nominated members of Parliament only.
State Participation	States/UTs (Delhi, Puducherry, J&K) participate.	States have no role.
Qualification	Must be qualified for Lok Sabha.	Must be qualified for Rajya Sabha.
Nomination Support	50 Proposers / 50 Seconders.	20 Proposers / 20 Seconders.

5. Census Constraints & 84th Amendment Act (intermediate)

To ensure uniformity in the scale of representation across different states and parity between the Union and the States, the Constitution mandates that the population of each state determines the weight of its votes in the Presidential election. However, this creates a political dilemma: if vote values were updated with every new census, states that successfully implemented family planning and stabilized their population growth would see their political influence diminish compared to states with high population growth. To resolve this, the 42nd Amendment Act (1976) originally froze the population figures at the 1971 Census level for the purpose of these calculations. Laxmikanth, M. Indian Polity, Chapter 18, p.187

This freeze was later extended by the 84th Constitutional Amendment Act of 2001. This Act specified that the population for the purpose of calculating the value of votes in the Presidential election (as well as the allocation of seats in the Lok Sabha) would continue to be based on the 1971 census until the relevant figures for the first census taken after the year 2026 are published. Laxmikanth, M. Indian Polity, Delimitation Commission of India, p.530. Effectively, this means that even in the most recent Presidential elections, the "population" used in the denominator of the vote value formula is not the current population, but the data from over five decades ago.

The result of this constraint is a fixed "value of vote" for each state's MLA until the year 2026. For example, an MLA from Uttar Pradesh carries a vote value of 208, while an MLA from Sikkim carries a value of 7, based entirely on their respective 1971 populations. Laxmikanth, M. Indian Polity, Chapter 18, p.201. This ensures that states are not penalized for demographic transition and maintains a stable federal equilibrium in the electoral college.

6. Principles of Uniformity and Parity (exam-level)

To ensure that the President of India truly represents the entire nation, the Constitution-makers devised a unique system of weighted voting. Instead of each elector (MP or MLA) having a single vote of equal value, their votes are assigned a numerical value based on two core principles: Uniformity among the States and Parity between the Union and the States as a whole. As noted in Laxmikanth, M. Indian Polity, Chapter 18: President, p. 188, this ensures the President is a representative of the Union and the States equally, preventing the election from being dominated by the Union Parliament alone.

The Principle of Uniformity ensures that the scale of representation of different States is consistent with their population. To calculate the value of an MLA's vote, we take the total population of the state (based on the 1971 census) and divide it by the total number of elected members of the State Legislative Assembly, further dividing the quotient by 1,000. Because populations vary, the vote value of an MLA from a populous state like Uttar Pradesh (208) is significantly higher than that of an MLA from Sikkim (7). This data is meticulously updated for each election cycle to reflect the constitutional formula Laxmikanth, M. Indian Polity, Chapter 18: President, p. 201.

The Principle of Parity establishes a balance between the Union and the States. This is achieved by ensuring that the total value of votes of all elected MPs is exactly equal to the total value of votes of all elected MLAs in the country. To find the value of an MP's vote, we divide the total value of all MLA votes across India by the total number of elected members of Parliament (Lok Sabha + Rajya Sabha). This mechanism prevents any single political party with a massive majority in Parliament from unilaterally deciding the Presidency without the support of the various State legislatures.

Feature	Value of an MLA's Vote	Value of an MP's Vote
Objective	Uniformity among different States.	Parity between the Union and States.
Basis	State Population / Elected MLAs.	Total Value of all MLA votes / Total elected MPs.
Variation	Varies from State to State.	Uniform for all elected MPs.

7. Calculation of Vote Values (MLA and MP) (exam-level)

In the Indian Presidential election, we do not follow a simple "one person, one vote" rule for the electors. Instead, we use a system of weighted votes. This is done to ensure two things: uniformity among the various states (so that a voter in one state has roughly the same influence as a voter in another) and parity between the Union and the States as a whole. To achieve this, the Constitution mandates a specific mathematical formula to determine the "value" of each vote cast by an MLA and an MP Laxmikanth, M. Indian Polity, Chapter 18: President, p.187.

The value of an MLA's vote is determined by the population of their state. The formula is: (Total Population of the State ÷ Total Number of Elected Members in the State Legislative Assembly) × (1 ÷ 1000). It is important to note that the "population" used here is still based on the 1971 Census, a measure taken to ensure that states are not penalized for successful population control measures. Because populations and assembly sizes vary, the value of an MLA's vote differs significantly across the country. For example, in the 2022 elections, an MLA from Uttar Pradesh held a vote value of 208, whereas an MLA from Sikkim held a value of only 7 Laxmikanth, M. Indian Polity, Chapter 18: President, p.202.

Once the total value of all MLA votes across all states is summed up, we calculate the value of an MP's vote. The goal is to make the total weight of the Parliament equal to the total weight of all State Assemblies combined. The formula is: Total value of votes of all MLAs of all states ÷ Total number of elected members of Parliament (Lok Sabha + Rajya Sabha). Unlike MLAs, every MP—whether from the Rajya Sabha or Lok Sabha, and regardless of their home state—has the exact same vote value. In the 2022 election, this value was 700 Laxmikanth, M. Indian Polity, Chapter 18: President, p.202.

Feature	MLA Vote Value	MP Vote Value
Basis	State Population (1971)	Aggregate of all MLA vote values
Uniformity	Varies from state to state	Uniform for all elected MPs
Objective	Uniformity among states	Parity between Union and States

8. Solving the Original PYQ (exam-level)

To solve this question, you must synthesize two critical concepts: the composition of the Electoral College and the weighted value of votes. As we studied in Indian Polity by M. Laxmikanth, the President’s election isn't a simple "one person, one vote" affair. Instead, it aims for Uniformity across States and Parity between the Union and the States. This is achieved by assigning a specific "value" to each vote based on the 1971 population of the respective State, ensuring that the election reflects the democratic weight of the citizens rather than just the raw count of representatives.

When you walk through the calculation logic, the answer becomes evident. The formula for an MLA's vote value is (Total Population of State / Total Number of Elected MLAs) × 1/1000. Because populations vary drastically between states like Uttar Pradesh and Sikkim, the value of their MLAs' votes must also differ significantly. Consequently, MPs and MLAs of different States have different numbers of votes (meaning their vote values vary), making (D) the correct answer. While all MPs share the same vote value among themselves, that value is derived from the total sum of all MLA votes, further distinguishing their voting power from that of individual MLAs.

UPSC often uses the "equality" trap to test if you understand the difference between arithmetic equality and proportional representation. Options (A), (B), and (C) are common pitfalls because they suggest a uniform equality that doesn't exist in this system. For instance, (C) is a classic distractor; while each member casts one physical ballot, the weight or value assigned to that ballot is the deciding factor. Always remember: in the Presidential election, the system is designed so that the weight of a representative is proportional to the population they represent, which inherently means those values cannot be equal across different states.
