Now that Mike Huckabee announced he's not running for President in 2012, Mitt Romney should really hope that Minnesota Congresswoman Michelle Bachmann jumps into the race.

Ramesh Ponnuru at National Journal says Bachmann won't win the nomination, but could help Romney in a big way.

Which candidate does Romney most need to worry about? In my view, it’s Tim Pawlenty. He can run to Romney’s right, but with establishment support, in a way that I don’t think Daniels or Huntsman can or want to.

(Bachmann) cannot win the nomination but can prevent anyone to the establishment candidate’s right from getting it either. So watch for Romney to start making a lot of positive comments about Bachmann.

I don’t believe Romney could win a Romney-Pawlenty contest. But he would almost certainly win a Romney-Bachmann race, and could well win a Romney-Pawlenty-Bachmann race. So to the extent he can boost her, it makes sense for him to do so. Having been on the losing end of this maneuver, Romney, I assume, knows how it’s done.
