You know, I keep saying this in other threads, and I'll say it here now:
You are all over reacting. All of you.
Step back for a moment and look at the election as a whole. The incumbents for the most part won in nearly all the national offices. There were exceptions and random senators and congressmen unseated, but for the most part the larger picture was, incumbents win. Which they statistically do.
You all are freaking out about Obama winning, but keep in mind, the GOP held the House and most of the Democratic gains in the Senate had more to do with unvetted idiots being idiots and losing elections.
So the country absolutely did not give either party a ringing endorsement of their policy or dogmas, it simply re-elected gridlock.
If there's a larger lesson for the DNC to learn, it's a question of why their candidates seem to do well in larger scale elections (Senate and President) but fall apart on the more local level (House).
For the GOP, the lesson is how do you take what's working on the local level (House races), and make it work at the national level. Especially, how do you sell a Southern Conservative world view to a place like Massachusetts where one of the few incumbent GOP Senators lost.
For the American People, I think the larger lesson is how do we bridge the extremes in politics to get actual stuff done. The People clearly don't trust either party enough to trust them with control of Washington. Following 2000-2006 (GOP years) and 2008-2010 (DNC years) I can't say I'd trust either party either. So what happens next?
The biggest challenge facing out nation isn't the apocalyptic scenarios you all laid out. It's how we find compromise and what does that even look like now?
