"During her interview last night, Barbara Bush described the Democrats vying for president as a "sorry" bunch of candidates. We should not be surprised. The mainstream media may try to make her out into some modern day Mother Theresa, but those of us who have been watching over the years know that's not the truth.
We remember her comment to the press after her husband debated Democratic vice presidential candidate Geraldine Ferraro in 1984. When asked what she thought of Ferraro, Barbara said she couldn't say it on television, but it "rhymes with witch."
