LV426 makes that claim. Everybody else knows it was the collapse of the housing market but she claims the tax cut caused the collapse.
Why did the Housing Market collapse?
Because of the dramatic weakening of underwriting standards for subprimes beginning in 2004 and extending through 2007, however Bush the Dumber was campaigning in 2004 on the fact that his tax cuts were "the economy's savior" and he "pointed to the strong housing market (again, in 2004) as proof".
So it's not me who ties Bush's Tax Cuts to Bush's Recession, it's Bush who did that.
