You mean his 1982 ad attacking McCain for being out of touch and not being able to open his e-mail? That kind of positivity?
EDIT: So the truth is vitriol now?
Wait a second, so now his age is an issue? People can be sharp and competent well into their 90's. If you're partisan, that's fine, vote for Obama, but don't vote Obama just because he's young, or African American or some other superficial reason, you vote the candidate you most agree with.
And Obama hasn't exactly been a choir boy either. The deal with Rezko. The sitting in a racist church for 20 years, spreading vitriol there about the CIA spreading AIDS to the black community and other crazy BS.
There's the voting against medical support for babies of botched abortions, which I feel is barbaric and uncaring. There's the Global Poverty Act, that necessitates a tax increase for an obscene amount of money to go to Kenya. Letting the Bush tax cuts expire, then INCREASING taxes on big businesses that will pass them on to the consumer.
I just look at it differently, that's politics, all about opinion. If you want to vote Obama, research him and make an informed decision.
