In a new 30-second spot airing in Wisconsin, former Massachusetts governor Mitt Romney touts his record as a “proven fiscal conservative” with quotes from columnists praising his work in Massachusetts.

“Conservative Record” was almost certainly made before Tuesday. But it works as pushback on yesterday’s firestorm, sparked when a Romney adviser unwisely compared the general election to an “Etch a Sketch” that erases what came before.

Many on both the right and left interpreted those words as proof that Romney would abandon his conservative positions once he won the Republican nomination.
