Charles Krauthammer accuses Rick Santorum and Michele Bachmann of "cheap shots" for attacking Mitt Romney for not signing a pro-life pledge.
"He's taken some shots from some of his competitors -- Santorum and Bachmann -- over this, and I think they're cheap shots, because he issued a very strong, pro-life statement which endorsed just about everything in the pledge.
.... I think he's made a strong statement. I'm not vouching for what lies deep in his heart. You can never do that with any candidate on anything, but his statement is extremely, strongly pro-life."
At issue: Romney's failure to sign a Susan B. Anthony anti-abortion pledge -- a decision he explained in a long post at the National Review.
Both Bachmann and Santorum hit him hard for his decision.
Meanwhile, Krauthammer has a more general on pledges.
"Every candidate ought to be allowed to frame a major issue in his own words. That's what's wrong with a pledge -- it's written by others, and it constrains you.
And that's why even pledges on taxes are not useful. You're not going to be able to say what you want. If somebody else writes it, it can be misinterpreted, and that's why I think that demanding that a Republican adhere to a pledge is not always wise."
