We've all seen some pretty sleazy commercials before, but this one takes the cake. It was produced by Yates Walker who was, until recently, the spokesman for the campaign of Tea Party Senate candidate Christine O'Donnell, who is challenging Rep. Mike Castle in the Delaware Republican primary. It is, hands down, the worst ad I have ever seen.
