The lack of enthusiasm is so pervasive that 67 percent of Republicans who responded to the CBS News survey couldn’t even pick one candidate from the current field who they’d be happy to support.

Seven percent of self-described Republicans said they were enthusiastic about Mitt Romney’s candidacy, and Michele Bachmann, who has stolen the spotlight in recent days, got the same backing. Two percent threw their backing to Herman Cain. None of the other candidates managed to garner more than 1 percent of the Republican respondents’ backing.
