Republican frontrunner Donald Trump has a huge lead in next week's biggest winner take all prize.

FOX's Jared Halpern has more from Washington:

Less than a week before Florida's 99 delegate winner take all Republican primary. A FOX News poll gives Donald Trump a huge edge over Senator Marco Rubio, the businessman up 43 to 20 with a big advantage among the state's early voters.

If the poll proves predictive, it could spell the end of the Rubio campaign. The Senator has banked his viability on winning his home state.

Ohio governor John Kasich is in a similar spot in his home state, but the FOX News survey shows the governor now leading Trump in Ohio by about five points within the margin of error.

In Washington, Jared Halpern, FOX News.
