Can someone please explain to me what an obama supporter is and what they are voting for?

Of all the Obama supporters I've talked to or heard about not one of them could formulate an intelligent answer. Many looked to the heavens and said BO was going to bring world peace, others said the only thing they care about that BO was going save the planet from global warming, cooling, change whatever. Not one of them could answer a single question on what BO stood for.

Maybe I've just been in contact with the stupid ones and there are BO supporters who have a valid reason or thought pattern as to why one should vote for BO.
