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.
