Voters may wait days for results in tight U.S. presidential race

Voters may not know the next U.S. president on election night, especially in close races. In 2020, Joe Biden was declared the winner days after the election, while Donald Trump won more quickly in 2016. In Pennsylvania, officials aim to report Election Day votes by 1 a.m. or 2 a.m. on Wednesday. This could help project the state's outcome early, but results will depend on other battleground states as well. Each state has different rules for counting ballots. For instance, Florida counts early votes before Election Day, while Pennsylvania waits to open mail-in ballots until then. Experts suggest results may take several days due to tight margins.
