Vice President Kamala Harris and former President Donald Trump are locked in a tight race for the White House. While millions of Americans have cast their ballot, many are still at polling stations exercising their franchise. Early election trends suggest the Republicans have an edge over the Democrats, but they say nothing is over until the swing states deliver their verdict. Like in the past, seven crucial swing states - Arizona, Georgia, Michigan, North Carolina, Nevada, Pennsylvania, and Wisconsin - are expected to play a major role in deciding the next president.

Trump has a slender lead in Georgia, North Carolina, and Wisconsin, while Harris leads in Michigan. Pennsylvania remains nearly tied, and the votes of the rest of the swing states are yet to be counted.

In Swing states, also called battleground states, the support for both parties is evenly matched. These states, unlike others that lean towards one party or another, remain political wildcards. Over the past few decades, they have shifted back and forth between the Republicans and Democrats, making them key to any presidential race.
