At the turn of the centry wasn't Great Britain and it's empire more or less as wealthy as the United States, with much of China's wealth being localized into several enclaves that were almost entirely owned by the Western powers?
I think it is delusional that the Republicans are going to be back in power with just the next eight years after the damage they've done to America; they've only been popular with voters with their appeal to religious tradition and anti-terrorist laws, but not with their corrosive economic policies that they have been obscured through seemingly generous tax breaks and that's what killed them (and the economy of course).
One domestic terrorist attack and just see how quickly people turn back to the Republicans.
Or the economic downturn persisting into 2010.
