The former veep backs Rubio and bashes Crist:

“Charlie Crist has shown time and again that he cannot be trusted in Washington to take on the Obama agenda because on issue after issue he actually supports that agenda.  Lately it seems Charlie Crist cannot be trusted even to remain a Republican. I strongly urge him to either stay in the Republican Primary or drop out of the race. The only winners from an independent bid by Crist would be Barack Obama and Harry Reid. “I am proud to stand with Marco Rubio and I urge all Florida Republicans, regardless of who you have been supporting, to unite behind him.”
