The Buzz is that Attorney General Bill McCollum will endorse Rudy Giuliani today when the presidential candidate is in Tallahassee. The former New York mayor will also meet with Charlie Crist, but don't expect the governor to make his endorsement any time soon. Later Giuliani will campaign in St. Petersburg and raise money in Naples.

UPDATE: Sure enough, McCollum stood by Giuliani after an appearance at the Governor's Club. McCollum said he will serve as statewide chairman of the campaign, adding: “Of all of the candidates, all the would-bes ... alone Rudy Giuliani has demonstrated the capacity and competence to lead our nation in the troubled years ahead."
