Rudy Giuliani and Mitt Romney turning their back on CNN Youtube debate?

Four days after the Democrat's 'landmark' YouTube debate in South Carolina, only Sen. John McCain (R-AZ) and Rep. Ron Paul (R-TX) have agreed to participate in CNN's next web-oriented debate.

"Aside from those two candidates, we haven't heard from anyone else," Sam Feist of CNN told the Washington Post.

"Rudolph Giuliani and Mitt Romney, both with dozens of videos on their YouTube channels, have not signed up," the Post reported Thursday on their popular campaign blog. "Neither have the rest of the Republican candidates, including Rep. Tom Tancredo (Colo.), whose 'Tancredo Takes' on his YouTube channel draw hundreds of views.

"Sources familiar with the Guiliani campaign said he's unlikely to participate," the Post's blogger added. "Kevin Madden, Romney's spokesman, said the former Massachusetts governor has seven debate invitations covering a span of 11 days in September." full story
