Florida Republican Marco Rubio will officially file to run for senate.
He'll fill out the official paperwork in Miami on Tuesday at 2 p.m.
Florida republicans have already chosen Rubio as the front-runner in the race for U.S. Senate.
With that senate filing deadline looming Friday, Governor Crist hints he'll make up his mind in the next several days whether he'll run as a republican, or an independent.
Crist is trailing behind rubio in the primary, and may have a better chance running as an independent.
Last week, the Florida GOP party issued a memo forbidding its members from supporting Crist if he decides to run as an independent.
