Do you really think if we had a Republican congress the US would be better off? Basically the world would be in a horrible economic state, but the US would be thriving? I really don't think it's something we can blame on a party.
What amazes me is that so much attention is used assigning domestic blame:
Except for China and its trading partners whose bubble has not yet popped the US ran into proportionally smaller problems than just about anybody else in the world. And the bubble was and is pretty much worldwide. Poland and Switzerland are the two countries that have gone through the bust and credible arguments can be made that they did better than the US.
That's pretty much the end of the story. Everyone else is waiting to see if they will have an economy after the China bubble pops. Most of the rest of the Americas may very well not. Canada, Brazil, Chile, Argentina and Venezuela are heavily dependent on the China bubble keeping on keeping on. Likewise Africa, the EU, Southeast Asia and Australasia. So we are headed for a second leg down and Obama can't do diddly about it because he is not the president/premier of China and even that would probably not help.
The China bubble is popping now, actually it began popping about 3-4 months ago when China's working age population started going down. It was 3.25 years from the time AIG bailed out of the CDS market due to increasing risk before we hit meltdown. China being the big construction boom is going to pop faster and cause more damage than the US bubble bust.
In sum witch hunting when there are no real witches strikes me as absurd.
