Will Florida be Marco Rubio's last stand? And can Bernie Sanders continue his momentum coming out of a surprise primary win in Michigan?

With Florida's delegates — and possibly a presidential nomination — at stake in Tuesday's primaries, our Florida Decides team is bringing you the "Florida Decides Presidential Primary Preview," a half-hour live special tonight to get you prepared.

  • LIVE CHAT: Join us for a live chat starting at 7 p.m. and let us know what you think about Tuesday's primary election.

Donald Trump recently shared on his Facebook page our exclusive News 13/Bay News 9 Florida Decides statewide poll that showed that 42 percent of likely Republican voters would choose him. But Rubio, who came in second in our poll, has been taking aim at Trump, battling for a win Tuesday in his home state. Florida's winner-take-all 99 GOP delegates could keep him competitive in the battle for the White House.

Meanwhile, on the Democratic side, it's not winner-take-all. In Florida, there are 214 delegates and 32 superdelegates up for grabs between Sanders and Hillary Clinton.

Four other states are holding primaries Tuesday: GOP candidate John Kasich's home state of Ohio, plus Illinois, Missouri and North Carolina.

In addition, several municipalities are holding nonpartisan elections for mayors, city councilmembers, county commission seats and more.

Will there be any surprises tomorrow night?
