MINNEAPOLIS -- New polls show Hillary Clinton appears to be extending her lead on Donald Trump in Minnesota and other key states like North Carolina, but Trump is betting that dissatisfaction with Obamacare can help him make some late gains with voters.

With just two weeks before election day, both Trump and Clinton focused their campaigns on the perennial swing state of Florida.

"The focus now turns, almost exclusively, to actually getting out the vote," said David Schultz, a political science professor at Hamline University.

Schultz says Clinton has a clear advantage in the polls, and on Tuesday she encouraged voters to get out the vote as way to combat Trump's claims of a rigged system.

"At the very moment when Donald Trump is making an unprecedented attack on our democracy, millions of people are registering, voting early, and volunteering in this campaign," Clinton said during a rally in Coconut Creek, Florida.

Trump took a different approach, pouncing on Tuesday's news out of the White House that premiums for Obamacare would be rising more than 20 percent on average.

"One of five Americans trapped in Obamacare will only have a single insurer to negotiate with in your state," Trump said during a rally in Sandford, Florida. "Congratulations. Lots of fun."

The criticism of Obamacare is a theme Schultz believes voters will hear plenty of from Republicans down the ballot as well.

"I think the Affordable Care Act has really become, with the rate increases, front and center to sort of national, state and local races across Minnesota and across the country," Schultz said.

But for Trump, if that message doesn't resonate in Florida, Schultz says it could be a quick election night.

"If Trump loses Florida we can almost say with certainty that he probably can't win the presidential election," Schultz said.
