Longer term, it's hard to tell what the lasting impact here is. Every pollster I've seen and talked to doing focus groups comes to pretty much the same conclusions:
1. People are very fed up;
2. People do not believe that what they do matters, because Washington and business are in collusion with each other;
3. Therefore, while more people generally agree with Democrats in terms of policy priorities, they do not support Democrats. They believe Dems are utterly ineffective and a total waste of time. As a result, they tend to simply tune out Democrats and what Democrats say.
Also long term, we are pushing the global financial system to really look for alternatives to the U.S. As it happens, we are in luck from a paucity of alternatives. Europe is looking worse, no one trusts Russia or China, Japan is looking in sorry shape, and emerging economies like Brazil are still too new. The list of stable countries with AAA ratings is fairly small, and they simply do not produce enough currency and sovereign debt to replace us.
But our position as the default is not a good long term strategy. Especially as we lurch from dysfunctional fight to dysfunctional fight.
