But Romney didn't want to do it in person. When McCain responded to Romney's claim of being misquoted in the AP by saying, "When you change issues — positions on issues from time to time, you will get misquoted," Romney didn't hit back. He pleaded for civility, saying, "Senator, is there a way to have this about issues and not about personal attacks?"

And another:

ROMNEY: But, look, you know, Governor, don't try and characterize my position. Of course, this war...

HUCKABEE: Which one?

(LAUGHTER)

ROMNEY: You know, we're wise to talk about policies and not to make personal attacks.

Romney has demonstrated a willingness to play hardball with his money and his purchased airtime, but tonight he shied from the fight.

There is something to be said for this, however. Nobody looks good getting beat up, but at times, Thompson's barbs looked churlish, McCain's looked bullying, and Huckabee's tarnished his aw-shucks rep. Giuliani may have done benefited the most from the whack-a-Mitt routine simply by not participating and looking like an adult.

For the record, the debate would have been much smaller but for a quirk in Iowa's primary system. The Iowa Democratic Party has a viability rule built in which means that any candidate who received less than 15 percent of the votes in a caucus room came away with nothing. Thus, candidates like Biden and Dodd who may have consistently polled around 10-14 percent received such a tiny fraction of the actual delegates that they were forced to drop out.

The Republican Party in Iowa has no such rule, which means that a number of candidates who would have done as poorly as Biden or Dodd in the Democratic side appeared to do fairly well and lived to see New Hampshire's snowy hills. As a result, the Republican debate was larger than the Democratic one, which David will post on later tonight.

Frankly, however, I don't think the Republicans mind having Ron Paul in there, just to take one example. When it comes to foreign policy, each of the Republicans is trying to identify themselves as the heavyweight, and keeping around a punching bag like Paul (who is more right than any of them, but is a one-man minority in these GOP forums) is a service to the rest of the field.

Oh, and PS — I liked Michael Scherer's characterization of Romney here.

Oh, and PPS — Kudos to ABC and its partners for running what was largely a substance-filled debate. They asked solid questions and allowed just the right amount of back and forth.
