From Thomas Mann, not exactly a partisan diehard, on the next two years:
There is simply no basis for meaningful bipartisan leadership meetings today. Republicans are determined to defeat Obama in 2012; they have no interest in negotiating with him in order to provide him any sort of victory. This is a partisan war and the Republicans are playing to win. The only question is how long it will take Obama to accept this reality and act accordingly.
Good question! My guess is....about 21 months.
