The President of India, the head of the Indian state, is elected indirectly by an Electoral College, rather than directly by the people. This method of election is designed to ensure that the President is a representative of both the Union and the States, and to maintain the parliamentary system where the Prime Minister and Council of Ministers are directly accountable to the Lok Sabha.

1. The Electoral College:

The President is elected by an Electoral College consisting of:

a. Elected members of both Houses of Parliament: This includes elected Members of Parliament (MPs) from the Lok Sabha (House of the People) and the Rajya Sabha (Council of States). b. Elected members of the Legislative Assemblies of the States: This includes elected Members of Legislative Assembly (MLAs) from all 28 states. c. Elected members of the Legislative Assemblies of the Union Territories of Delhi and Puducherry: These two Union Territories have legislative assemblies and their elected members also participate in the presidential election, as per the 70th Constitutional Amendment Act of 1992.

Note: Nominated members of Parliament, State Legislative Assemblies, and members of Legislative Councils (where they exist) do not participate in the presidential election.

2. Method of Election: Proportional Representation by means of the Single Transferable Vote:

The election is held in accordance with the system of Proportional Representation by means of the Single Transferable Vote (STV) and secret ballot. This system ensures that the winning candidate secures a clear majority of votes, reflecting a broad consensus.

3. Value of Votes:

To ensure uniformity in the representation of different states and parity between the states as a whole and the Union, a specific formula is used to calculate the value of each vote:

a. Value of an MLA's Vote: The value of an MLA's vote is calculated based on the population of the state they represent. The formula is:

`Value of an MLA's Vote = (Total Population of the State / Total Number of Elected MLAs in the State) x 1/1000`

*Note: The population figures used for this calculation are based on the 1971 Census (as per the 84th Amendment Act of 2001), which will remain in effect until the first census after 2026. This is to avoid penalizing states that have successfully implemented population control measures.*

b. Value of an MP's Vote: The value of an MP's vote is uniform across all MPs. It is calculated by dividing the total value of votes of all elected MLAs of all states by the total number of elected MPs of both Houses of Parliament.

`Value of an MP's Vote = (Total Value of Votes of all Elected MLAs of all States / Total Number of Elected MPs of Parliament)`

4. Quota for Election:

To be declared elected, a candidate must secure a fixed quota of votes. The quota is determined by the formula:

Electoral Quota = (Total Number of Valid Votes Polled / (Number of Candidates to be Elected + 1)) + 1

Since only one President is to be elected, the formula simplifies to:

Electoral Quota = (Total Number of Valid Votes Polled / 2) + 1

This means a candidate must secure more than 50% of the total valid votes polled.

5. The Voting Process (Single Transferable Vote):

a. Voters (members of the Electoral College) do not simply vote for one candidate. Instead, they mark their preferences against the names of all candidates (1, 2, 3, 4, etc.). b. In the first count, only the first preference votes are counted. c. If a candidate secures the required quota based on first preference votes, they are declared elected. d. If no candidate secures the quota, the candidate with the fewest first preference votes is eliminated. Their second preference votes are then distributed among the remaining candidates. e. This process of elimination and transfer of votes continues until one candidate secures the required quota or until only one candidate remains, who is then declared elected.

This complex system ensures that the President is elected by a broad consensus, representing both the Union and the States, and upholds the federal character of the Indian polity.
