In the last days before the vote, Democrat Kamala Harris and Republican Donald Trump were campaigning hard in swing states, particularly Pennsylvania, which has the most Electoral College votes of the battleground states.
How does the Electoral College work?
Every four years, a temporary group of electors is created — and it’s technically these people, not the American public, who vote for the president.

There are 538 electors in total, who are expected to vote for the winner of the popular vote in their state (or in the case of two of Nebraska and Maine’s electors, the winner of each congressional district), but it’s not a legal requirement everywhere.
What happens if nobody gets 270 votes?
The second way this could happen would be if so-called “faithless electors” choose to vote for someone who is not Harris or Trump for president.
This has only happened twice — in 1800 and in 1824.
