Florida is up for grabs on Tuesday with primary voting.

FOX's Eben Brown reports:

Marco Rubio is hoping his Florida neighbors will come through for him:

(Supporters) "Marco, Marco, Marco!"

Rubio rallied his supporters this morning in Jacksonville:

(Rubio) "We're gonna win the 90 delegates here in Florida."

And those delegates will go to a single Republican winner here tomorrow night.
