Here's a quick guide on how the President is elected:
The President of India is chosen by the Electoral College, which consists of 4,896 members - 543 Members of Lok Sabha, Members of Rajya Sabha (233) and total members of State Assemblies (4120).
While the Lok Sabha Speaker, an elected member, can vote, the two nominated members in the Lower House from the Anglo-Indian community cannot. Twelve nominated members in Rajya Sabha are also ineligible, news agency Press Trust of India reported.
Voting for the Presidential elections is however different from other elections. Each MP and MLA vote has a certain value attached to it. And this value differs from state to state. While an Uttar Pradesh legislator's vote has a value of 208, the value of votes of their counterparts in Arunachal Pradesh is just 8. Same goes for Parliamentarians.
The total value of votes in the Presidential elections is 10,98,903 - 5,49,408 for MPs and 5,49,495 for MLAs. A candidate needs to secure 50% of the valid votes polled +1.
The counting of votes will take place on July 20 in New Delhi where all the ballot boxes will be brought from various state capitals.
So far 13 Presidents have been elected to the post. In the 2012 elections, incumbent President Pranab Mukherjee, who was UPA nominee, had garnered 7,13,763 votes, while Pratibha Patil, another UPA nominee, secured 6,38,116 votes in the previous polls in 2007.
A total of 13 vacancies in Lok Sabha and state assemblies will be filled up after the presidential elections.
