I think the Republican strategy to say that Obama is a “ nice guy but a bad president” is get the older generation to think of Jimmy Carter.
Evidently Clinton won’t tell the Obama campaign what the content of his speech will be at the convention. They keep calling and asking, which is making him madder & madder. Clinton does ads, makes statements, etc. ‘for’ Obama, but when you really look at what he’s saying or more often, what the downstream effect is, it does not help Obama. It is very subtle sabotage .... no love lost between Bill & Barack. :-)
