Romney Going for the Jugular

The Romney campaign just released this very effective ad, that attacks Newt for his boneheaded criticism of the Paul Ryan Medicare plan earlier this year on Meet the Press.

My only question is why did the Romney team include Pat Buchanan in the ad? They couldn’t find any other conservatives who are critical of Newt that are not Israel bashers? Criticism from Pat Buchanan will not resonate with most Republicans.
