(CNN) - The governor of Florida, now running an independent bid for senate, says sour grapes didn't lead him to leave the Republican primary.
Gov. Charlie Crist told CNN Chief Political Correspondent Candy Crowley that he is aware of criticism that he withdrew from the primary only after his political fortunes fell against former Florida House Speaker Marco Rubio, who is expected to win the Republican nomination handily.
"That's what parties do and that's part of the biggest problem … all they're going to do is attack each other all day long. People like this, they go home and watch cable television, watch broadcast television and they see those kinds of arguments and it breaks their hearts," Crist said in an interview to be aired Sunday on CNN's State of the Union. "They see bickering, and they see nobody standing up and saying, 'We're all Americans, we've gotta to work together.,'"
Crist will face off against the party nominees – likely Rubio and Democratic Rep. Kendrick Meek - in November. Several other candidates have qualified for the election without party affiliation, but none are expected to seriously contend for the seat.
