The centrist Crist has toyed with the idea of dropping out of the primary and running as an independent against Rubio and Democratic candidate Rep. Kendrick Meek.

"Lately it seems Charlie Crist cannot be trusted even to remain a Republican," Cheney said in a statement. "I strongly urge him to either stay in the Republican Party or drop out of the race.
