1 Inexperienced. Obviously. A Senator for 3 measly years.
2 No record of accomplishment. In one of his major primary victory speeches Obama told a pathetic story of organizing a jobs fair - that NOBODY attended.
3 A bore. Yes, Obama can give a good speech, but he seldom does.
4 A blowhard. Obama is a young Harvard law graduate who has become extremely impressed with - himself. This blowhardiness extends to his spouse, the subject of point 5.
5 His wife Michelle is a problem. She is arrogant and gives his empty rhetoric a more strident character that is already starting to frighten people.
6 A leftist. Obama is an out and out leftist, a young George McGovern, and it will be impossible to hide that fact much longer. For example:<7>AGAINST the War on Terror. Obama says in almost every speech that terrorism is being "used to scare voters". Few Americans are that naive or left wing.
That's a short list, there are more, and I think most Americans will realize that Obama is a flash in the pan.
