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.

Asked if the statement was helpful for Republicans, Chambliss said on CNN's "State of the Union" Sunday "Probably not. But in politics, everybody is entitled to their own opinion.

"You jump on one side or the other in these races and that's probably what happened," he said. "It's certainly stepped up the rhetoric."
