It is really quite simple. Nobody likes Mitt Romney, not even his friends. Face it, the guy is a stuffed shirt. George W. Bush may be detested by even Republicans, but he is likable. Mitt's surprise speaker should have been W. having a beer with Clint Eastwood.
Could not find a clip of Mitt having a beer.
However, W. knows the meaning of the word "party."

I rest my case.
