Vilsack stumble?

Congressman Steve King was once again the obvious winner in Tuesday night's debate at Morningside College... Christie Vilsack was not even able to answer a simple "yes" or "no" to a question from a moderator when asked to do so. She had done this during all of the debates so far. Vilsack begins answers to her questions in that manner, then seemingly becomes frsutrated and finally attempts to smear Congressman King, his character, his policies, and whatever else seems to slip into her mind.
