As the election sets itself up to be won and lost on a razor's edge, the results in Wisconsin and Michigan may determine who will become the next president.
Wisconsin is such a reliably blue state that Democratic nominee Hillary Clinton had not set foot in it since winning the Democratic primary, and Republican nominee Donald Trump canceled a rally there just days before the election, reports CNN's live broadcast.
But with 68 percent of Wisconsin votes counted, Trump is leading in the state with 49 percent to Clinton's 46 percent. Meanwhile, in Michigan, the race remains neck-and-neck, with the pair within one point of each other.
Mordecai Lee, a professor at the University of Wisconsin-Milwaukee, told WITI that the candidates' recent visits indicate their confidence levels in the states:
Hillary Clinton hasn't been in Wisconsin for the general election. That tells us that she thinks she's in pretty good shape -- but she's sending her VP candidate, who's been here a half-dozen times, which tells us she's not positive. She wants to be sure. Donald Trump has been here a few times. He's sent his VP candidate a few times. I think that means he's on offense and Clinton is on defense. Trump really wants to win Wisconsin. On the other hand, Clinton wants to prevent him from winning Wisconsin.
As Trump continues to pull ahead throughout the night, with a Florida win, a lead in Iowa and a projected win in Nebraska -- where he is expected to win four of the state's five electoral votes, since it does not use a winner-takes-all system -- experts say that Clinton needs to win Pennsylvania, New Hampshire and Michigan to stop him from pulling off an upset win that the vast majority of pollsters and pundits dismissed.
Clinton has also won Oregon and Washington and is leading in Pennsylvania.
"Ten electoral votes in a close election can mean the difference between who's president and who isn't, and so I think when Trump tries to figure out the math, it's like a puzzle, moving the states around," Lee said. "When the campaign tries to figure out how to get to 270, 10 votes from Wisconsin suddenly become really important."
