What time do polls close in swing states on Election Day 2024 ...

Who wins the 2024 election for United States president likely will come down to results in seven swing states.

Wisconsin, Michigan, Pennsylvania, Arizona, Georgia, Nevada and North Carolina are the battleground states to watch in the race for U.S. president as Election Day polls close on Tuesday. Why? Because these are the states likely to deliver the Electoral College votes needed for the winning candidate to get a majority of 270.

The states, visited by Vice President Kamala Harris and former President Donald Trump the most, stretch across four different time zones.
