Bush come into office with a budget surplus, a relatively healthy economy, growing GDP, and a combination of regulation and oversight that allowed the banks to prosper without getting out of had.
Bush then de-regulated banking enough to change oversight, took the surplus and reversed it into the largest deficit we have ever seen, took us into two wars while lowering the tax based income to the fed, and presided over the beginning of recession.
I think that certainly indicates that Bush had a very heavy hand in bringing the recession on.

2017-? (Probably): Dissent is the highest form of misogyny.
