To be honest, I think Bachmann is making a play for Romneys VP spot, by virtue of never attacking him, and only attacking anyone to the right of him. On the Fallon show, she seemed almost "smitten" with him. It's disappointing me, she's become his attack dog. If she wants to score points, take the gloves off and go after him.
“If she wants to score points, take the gloves off and go after him. ..”
That would be a good call to the Mark Levin show, because maybe he’ll clue her in.
She is not vying for his voters, why should she attack him and alienate them for no good reason? Bachmann's potential pool of voters are the anti-Romney movement conservatives and Tea Party folks.
If the time comes where Bachmann is fighting for the same voters as Romney, she will attack him without reservation. As of now, there just isn't much point.
