WASHINGTON — The next hour could make clear who will become the next president of the United States.
Polls close at 7:30 p.m. ET in North Carolina and Ohio. Results start rolling in from Florida and Pennsylvania next.
If Hillary Clinton wins one or two of those states, she may be impossible to beat.
Donald Trump is counting on a better-than-expected turnout among working-class voters in to compensate for anticipated losses among minority and college-educated voters.
A Clinton win would make her the first president in the country's 240-year history.
It would also allow Barack Obama to make history again: By joining Franklin Roosevelt and Ronald Reagan as the only postwar presidents to have a successor extend their party's time in the White House beyond two terms.
