There is a key bloc of Republican voters whose ambivalence has turned the GOP nomination contest into an erratic mix of roller-coaster ride and dating game. They flirted with Donald Trump and then embraced Rep. Michele Bachmann (R-Minn.) before jumping on and off the Rick Perry bandwagon. At different times they yearned for Govs. Mitch Daniels of Indiana and Chris Christie of New Jersey and, always, some have cast a longing eye in the direction of former Alaska governor Sarah Palin.
The one point on which they have been most consistent, however, is their resistance to the candidate who has been making his case the longest: former Massachusetts governor Mitt Romney.
