Gov. Charlie Crist played cat-and-mouse with CNN Miami reporter John Zarrella on the subject of whether he might be John McCain's VP choice. "Possible McCain running mate," read a banner at the bottom of the screen as Crist took CNN on a walking tour of the mansion grounds -- including the solar-heated swimming pool.

"If you were asked, what would you say?" Zarrella asked Crist. "Well, I've got to continue to work hard as the governor of Florida, and I haven't been asked, so it's really kind of moot at this point." Crist and McCain were shown campaigning at a restaurant and in St. Pete. "If in some small way an endorsement here or there helps him along the way and along his journey, so be it," Crist told CNN.
