Obama has done more with to hurt the economy by chasing his agenda than bush did.
Bush started the two big wars we're still knee-deep in. Libya was over in months, no lives lost, minimal cost - iraq and afghanistan were HUGE drains on resources, and we had to BORROW to pay for it, instead of raising taxes.
Bush tax cuts were a drain on the economy- a quick bump but then they're now required just to maintain the recession!
And Bush gave over 3 tril in bailsouts - obama has given 787 billion.
So while obama sucks and I hope his birth cert keeps him out of a second term - the really BIG things that bush did are probably bigger. Unless you can name something bigger than 3 tril in bailouts and two vietnams?
