From what I've read, Mary Matalin is NOT his top campaign advisor, and even if she were, she likes to WIN, so she wouldn't be doing anything to mess up her candidate's chances.
I didn't even watch the debate, so I don't know what the video was about. What I HAVE read, from various sources, was that Fred came off very well in the debate, especially since he wasn't part of the bickering that was apparently going on between Rudy and Mitt. I haven't read anything about any negative ad he showed, so it must not have been made too unfavorable an impression on those who wrote the articles I read.
I don’t view it as an attack when you use the opposition’s own words against them.
