America will vote for its next President on November 5, Tuesday. The US election, held once every four years, takes place on the Tuesday following the first Monday in November, as spelled out in the US Constitution.

Initially, the 2024 US election was a re-match of 2020 but it was upended in July when President Joe Biden ended his campaign and endorsed Vice President Kamala Harris for the top post. On July 21, Joe Biden quit the White House race amid growing calls within his Democratic Party for his stepping down. Americans will also be voting for members of Congress, who play a key part in passing laws that can have a profound effect on American life.

-The winner is not the one who gets the most number of votes but both the candidates compete to win contests held across the 50 states. Each state has a certain number of so-called electoral college votes partly based on population. There are a total of 538 up for grabs, and the winner is the candidate that wins 270 or more, according to a BBC report.

-Whichever candidate wins the highest number of votes is awarded all of the state's electoral college votes. Most states lean heavily towards one party or the other, so the focus is usually on a dozen or so states where either of them could win. These are known as the battleground or swing states.

-Usually the winner is declared on the night of the election but it could take a while. If there are close margins in key states, it could take days to determine a winner.
