The NRSC will endorse Florida Gov. Charlie Crist (R) for U.S. Senate today, Politico reports, "marking the first time it has taken sides (for a non-incumbent) in a competitive GOP primary this election cycle."
"The committee's decision will make it tougher for former Florida House Speaker Marco Rubio (R) to raise money against Crist, given that the party has given the governor its stamp of approval."
One thing to point out: Only registered Republicans can vote in Florida's GOP primary, so despite Crist's popularity among independents and Democrats, it could be a close race.
Update: Rubio tweets: "Disappointed GOP
senate comm endorses Crist on day 1. Remember that reform must always
come from the outside. Status quo won't change itself."
