Republicans can't say they weren't warned about Mitt Romney.

As the party's nominee reels from gaffe to gaffe, they might recall Newt Gingrich's comment last winter: Mitt Romney, he said, was the weakest Republican front-runner "since Leonard Wood in 1920."

Leonard who? Exactly.

The writing was on the wall for this campaign as long ago as January 10. That was when New Hampshire held its presidential primary, and Romney showed he couldn't even get 40 percent of the Republican vote in what is, in many ways, his home state.
