Consider: The stunt costs her nothing. It compromises nothing in the way of her conservative ideology. And it puts no new distance between her and the McCain agenda.
And yet (if the Maine media is dumb enough to swallow it) it allows her to frame herself as a moderate to middle-of-the-road voters.
But think about what it means.
Two years into a campaign from Sen. John McCain (R-AZ) full of irresponsible statements and troubling proposals, the one issue Collins has chosen to separate herself from him on has to do with tactics.
Not McCain's economic policy. Not his Iraq policy. Not his plan to tax health insurance benefits. Collins doesn't seem to have much problem with the substance of McCain's plans for America.
She just wants him to give them a softer sales pitch.
