AKIPRESS.COM - Americans are voting in one of the most divisive presidential elections in decades, pitting incumbent Republican Donald Trump against his Democratic challenger Joe Biden.
The first polls opened from 05:00 EST (10:00 GMT) in Vermont.
Nearly 100 million people have already cast their ballots in early voting, putting the country on course for its highest turnout in a century, BBC reports.
Both rivals spent the final hours of the race rallying in key swing states.
National polls give a firm lead to Mr Biden, but it is a closer race in the states that could decide the outcome.
In the US election, voters decide state-level contests rather than an overall single national one.
Among the first states to begin election-day voting on Tuesday are the key battlegrounds of North Carolina and Ohio (11:30 GMT), followed half an hour later by Florida, Pennsylvania, Georgia, Michigan and Wisconsin. Arizona will follow at 13:00 GMT.
