At this point, I'm convinced that the Dems will come within an asshair of the House, but just shy. On the bright side, it will force the House GOP into some really uncomfortable positions, many of which will require near-impossible party discipline..
I'm still thinking that the Grand Showcase Prize in this showdown comes from changing the Senate filibuster rules - allowing Obama to flood the Judiciary with young, healthy, liberal judges. That'll leave a mark on government for a long, long time; it'll be 2050 and beyond, and we'll still be cheering the rulings written by his judges.
