Florida Senator Marco Rubio is pushing hard to win his home state next week, but says his supporters should also try to derail the frontrunner in another winner-take-all contest.

FOX's Jared Halpern explains from Washington:

Polls show Marco Rubio needs to come from behind to beat Donald Trump in Florida. All 99 of the state's delegates go to the winner.

Ohio is also winner-take-all and Rubio concedes he's unlikely to win there:

(Rubio) "Clearly John Kasich has a better chance of winning Ohio than I do and if a voter in Ohio concludes that voting for John Kasich gives us a better chance of stopping Donald Trump there, I anticipate that's what they'll do."

The latest FOX News poll shows Ohio Governor John Kasich leading Trump in the Buckeye State by a single digit margin.
