You apparently have forgotten that the tax cuts, which were passed in 2001, were forced by Senate Democrats to be back-end loaded. The first year "cut" (2002) was nothing but a small rebate to the middle class, which nobody, not even Democrats, believed would change anything. Then the 2003 cuts amounted to only 10% of the cuts, and the 2004 cuts amounted to only 20%. So 70% of the tax cuts did not even take place until Bush's second term.
And remember how well the economy was growing in 2006? and how much revenue we took in? Remember that the deficit in 2006 was only $170 billion?
