Romneyworld strongly believes that if Palin gets in, he wins more easily. “The shock value would cause elected officials and party officials to rally around Mitt, because she’d scare the daylights out of them,” one official said. “And it would allow him to position himself very much in the middle of Republican, conservative thinking and avoid the fringe, and look more moderate for the general election.” Rep. Michele Bachmann would have the same effect, the adviser said. Either of them “gives Romney a bogeyman: ‘Stop this crazy woman.’”
A Romney attack on Bachmann of that nature may be the one thing that could lead her to help out Pawlenty.
As for Palin, the Romneyites might be right about her effect on his primary campaign. But she could do serious damage to his ability to win a general election. I wrote about all of this a few months ago.
