In Nevada, the Romney campaign held one such call featuring former Rep. Barbara Vucanovich, a Republican who served with Gingrich in the House from 1983 to 1987. “I did serve with the Speaker and he really used to be erratic and I think he probably still is,” Vucanovich said in a January 31 conference call. “One of my feelings with him is he was always so full of himself. I mean, humility was not in his makeup. And he was cocky and arrogant and of course didn’t listen to anybody.”…

What no one mentioned in the conference calls was that in 2005 Vucanovich, the first woman ever elected to Congress from Nevada, published a memoir, Barbara F. Vucanovich: From Nevada to Congress, and Back Again. She discussed Gingrich at several places in the book, and said a number of complimentary things about him…

Needless to say, the Romney team did not include Vucanovich’s praise of Gingrich on a conference call intended to criticize him. But the key part of all this is that Team Gingrich did not push back. You can rest assured that if the Gingrich campaign enlisted a surrogate to attack Romney, and that surrogate had in the past praised Romney, the Romney campaign, run by some of the country’s best opposition researchers, would have made sure reporters knew that, effectively neutralizing the attack. But Gingrich just doesn’t have the resources, or the money, or the inclination to fight that battle. At this point in the race, the Romney campaign knows its charges will go unanswered in any systematic way, even if there are good answers to be given.
