Bachmann's run is improving Romney's chances at the nomination

The candidate who could play the Buchanan/Huckabee role this time is Michele Bachmann. Like her ‘96 and ‘08 counterparts, she cannot win the nomination but can prevent anyone to the establishment candidate’s right from getting it either. (I think she has greater potential strength in the primaries than Santorum, but if he took off he could play the same role.) 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.
