President Donald Trump appears to have lost some support among white men and older people in Georgia and Virginia, key parts of his voter base, according to Edison Research polls.
While Trump is still winning the majority of those voters, some of them switched to supporting his Democratic opponent, former vice -president Joe Biden, the exit polls show.
Edison's polls show Trump winning seven in 10 white men in Georgia, which is down from an eight in 10 advantage over Democratic nominee Hillary Clinton in 2016.
And while Trump is winning six in 10 voters who are at least 65 years old in Georgia, that is down from a seven in 10 four years ago.
Final election results from both states have yet to be tallied but Biden has been projected to win Virginia. Clinton also won the state in 2016.
In Virginia, Trump was winning six in 10 whites without college degrees, down from seven in 10 in 2016. Trump was also winning six in 10 white men in Virginia, down from seven in 10 in 2016.
In more encouraging news for the president, Trump was winning six in 10 voters in Virginia who have an income of $100,000 or more.
The poll is based on in-person interviews with voters on Tuesday, in-person interviews at early voting centres before Election Day and telephone interviews with people who voted by mail.
