*IF* the US defaults, Obama will be blamed, simply due to the prevailing social mood right now. The president is always the focus of blame, whoever he may be.
I think that everything is Bush's fault. Just ask 'the chosen one'. Modern political correctness demands accountability; therefore, Bush. But if anything good happend, that came from Clinton.
It will revolves around the chess game that leads up to the default. Those who play the end game the best will succeed in letting the weight fall on the other side.
That said, I think the odds of an actual default are no higher than 1%. A deal will be done to kick the can down the road.
You are not a patriot when you can't blame such treasonous act on a foreign entity, such as BRICKS, US has such burden, so other countries can enjoy peaceful and productive world order. Blame Canada.
FOX will blame Obama and the democrats. MSNBC will blame Bush and the republicans. Democrats will blame republicans and corporate America. Republicans will blame democrats and unions. I blame Ronnie Rayguns. He set the trend of kicking the can down the road with no oversight. We've run out of road.
