MYRTLE BEACH, SC — After a debate in which Republican frontrunner Mitt Romney faced attacks from all sides, the Romney campaign says it has not yet accepted invitations to participate in two high-profile debates leading up to the January 31 Florida primary, and a key Romney adviser is expressing fatigue and frustration over what he sees as a never-ending series of GOP debates.

“There are too many of these,” Romney strategist Stuart Stevens said after Monday night’s Fox News debate at the Myrtle Beach Convention Center.  “We have to bring some order to it.  We haven’t accepted Florida…It’s kind of like a cruise that’s gone on too long.”
