After one primary, CNN says Rudy is quitting and endorsing McCain:

Rudy Giuliani will endorse John McCain Wednesday, two GOP sources familiar with the discussions told CNN Tuesday.

McCain’s campaign manager, Rick Davis, had been in “ongoing discussions” with Rudy Giuliani’s campaign about the former New York mayor ending his run and endorsing McCain’s candidacy, according to a GOP official familiar with talks.

CNN projected that Arizona Sen. McCain would win the Florida GOP primary Tuesday night, beating former Massachusetts Gov. Mitt Romney, with Giuliani in a tight race for third with former Arkansas Gov. Mike Huckabee.
