Filibuster vs. Reconciliation
I think the GOP overplayed its hand. Forcing a filibuster proof vote on every issue forced the Dems to take a page from the George W. playbook, using reconciliation to push through major legislation. Tit-for-tat, and the dance goes on. There is no essential difference between the Dems and GOP because in the end, nobody wants to upset the applecart. Wildcard in the mix is Barack Obama. Neither Dems nor GOP quite know what to do with him. (same way they were equally mystified when Baye bowed out). Debate the merits, but Obama seems like he actually wants to get things done.
