Unlike some of the other presidential candidates' spouses, Callista Gingrich has not played a very public role in her husband's campaign but recently on her Twitter feed, she re-tweeted two hits at Mitt Romney written by a Gingrich supporter with the Twitter handle @UnitedStates.
And the other one, a reference to yesterday's "FOX News Sunday" interview with Romney.
"Poor Romney. He just is a sound bite candidate. Chris Wallace pulled the string from his back, and he spewed consultant apprvd policy #tcot ", it says.
Gingrich and his campaign have mostly avoided going negative, focusing on what the former Speaker of the House calls "positive ideas and positive solutions."
