It's not that simple. Tell me how Clinton's economy would have fared if 9/11 had occurred early in his term, and how Clinton would have managed without the dot-com bubble.
I do blame GWB, as well as many in congress, and Clinton (mortgage backed securities) too, for the 2008 crash.
There is a CBO study that shows there is no significant correlation between marginal income tax rates and the growth of GDP. In fact the report goes on to show that the biggest effect of lowering marginal income tax rates was the concentration of income at the top.
I’ll try and find the link again.
