Callista Gingrich Jabs Mitt on Twitter

Formerly behind-the-scenes political wife Callista Gingrich is getting in the ring to support her husband—by knocking his opponent on Twitter. Granted, she did not come up with the insults herself. Instead, Callista retweeted others’ digs at Mitt Romney. “Mitt’s ‘Money Never Sleeps’ photo. I personally don’t mind it, but won’t play well in Ohio,” wrote one Gingrich supporter. “Poor Romney. He just is a sound bite candidate. Chris Wallace pulled the string from his back, and he spewed consultant approvd policy,” tweeted the other. As the race drags along and continues to get tighter, it seems even the Gingrich campaign may be losing its positive attitude.
