MIAMI, FLORIDA - Republican presidential frontrunner Donald Trump is getting ready to mount a major fight in Florida against two of the state's resident sons.
 
Jeb Bush led Florida as a two-term governor and Marco Rubio has been a senator since 2011.

But the billionaire businessman is outpacing both in early polls. His team is hoping to maintain that advantage with a heavy investment in the state.
 
Trump will arrive Friday for a two-day swing - his first as a presidential candidate - with rallies planned in Miami Friday evening and Jacksonville on Saturday.

Trump recently brought on a Florida state campaign director and plans to open a Sarasota office in early November.
 
The campaign is also expected to announce the hiring of multiple state co-chairs soon.
