Part of the reason he’s risen so quickly is that he’s been able to tout his executive experience. But this approach brings unique vulnerabilities, and some conservative activists in Iowa are starting to express doubts about whether Walker’s gubernatorial record is as conservative as it sounds. That Des Moines Register poll may offer a little insight: Walker was the No. 2 choice for those looking for an establishment nominee and for those looking for an anti-establishment one.

“He’s in a sweet spot,” pollster J. Ann Selzer told the paper. “People who don’t want an ultra-conservative think he’s OK. People who don’t want a moderate think he’s OK.”

So at the moment, Walker is all things to all men. That may not last. On two of the issues nearest and dearest to the conservative base, Walker’s positions are a little blurry. His record shows there could be openings for primary contenders running to his right—think Sens. Rand Paul and Ted Cruz—to try to peg him as a squishy RINO–surrender-caucus member.
