ATLANTA -- Atlanta is hosting several potential vice presidential prospects as the Republican Governors Association meets in Atlanta this week.

Minnesota Gov. Tim Pawlenty will speak at the RGA's luncheon on Wednesday. He's been mentioned as a possible running mate for GOP presidential nominee John McCain.

Also on hand is another possible No. 2: Florida Gov. Charlie Crist.

Crist and Georgia Gov. Sonny Perdue have been locked in a battle over water rights between their two states. But the two seem to be bonding over baseball.

Crist and Perdue attended the Atlanta Braves-Florida Marlins game Tuesday night at Turner Field, where both threw out ceremonial first pitches.
