In North Carolina, the race is also very close and more than four million people have already cast their votes.
It’s a state that has voted for a Republican candidate in nine out of the last 10 presidential elections.
Donald Trump won it in 2016 by four points.
It was the women of the state that helped carry the president to victory and in just four days time, they could, once again, be the deciding voters.
