Who knew Michele Bachmann was so sensitive about being asked if she’s a “flake?”

Poor Chris Wallace — he issued one of the most abject apologies I’ve ever seen from a Fox News host, but Bachmann is still miffed.

ABC News’ Jon Karl, who’s been getting face-time with Bachmann in Waterloo in advance of her formal campaign announcement, played a clip of the web video in which Wallace said, “I messed up. I’m sorry.”

When Karl asked if she accepts the apology, Bachmann brushed aside the question this way: “I think that it’s insulting to insinuate that a candidate for president is less than serious.”

Trying the question again, Bachmann replied, “Those are the small issues. I’m focused on the big ones.”
