It took 8 years for corrupt Mr GW Bush Junior to screw our economy; How long will it take for Obama to fix it?

The economy was in real good shape in 2007 when the dems took over Congress. The deficit was $165 billion and unemployment was 4.5% Now after 4 years of democrats - Obama was in the Senate for 2 of them - the deficit is TEN times that and unemployment is double. How is that Bush's fault?
