First, the Congress is not controlled by Republicans. Only the House is, so two thirds is still under control of Dems with the president and Senate. I think you are purposely knit-picking your statistics to try and advance the Dem point of view. When GW took over his office, Dems had imposed a recession at the end of the Cointon Administration. Shortly thereafter, 911 happened that also slowed the economy. The economy did turn around until Barney Franks and Maxine Waters made a backroom deal with Fanny and Freddie to torpedo the economy with bubble loans for everyone. They timed the maturity of the loans to coincide with the end of Bush's term. It worked very well.
The difference is the unemployment then was about 5% to 20% now.
