Or so says Bob Novak, in a column that strongly suggests that the McCain campaign is behind the dirty trick:
Publication of Rudy Giuliani's secret campaign plan has so embarrassed Florida's new Gov. Charles Crist that supporters of Sen. John McCain fear it might backfire against their campaign for the Republican presidential nomination.
The 140-page dossier was found on a Crist aircraft during his campaign for governor when former New York City Mayor Giuliani was in Florida supporting him. With an early 2007 test scheduled for Florida, Crist's support could be critical. McCain has been considered the early favorite to win his backing.
Some McCain supporters fear Crist might be offended by efforts of John Weaver, McCain's political adviser, to take advantage of the misplaced Giuliani document. "I thought it was a security company," Weaver said of Giuliani's consulting company. His comments prompted speculation that Weaver was responsible for making the dossier public.
