Today over at TAP I have one developing an idea that comes from Sarah Binder: that the Speaker has replaced the Hastert Rule with a Boehner Rule of "Make the Senate Go First." It's actually a two-track process. When the party wants things to pass, they let the Senate negotiate out deals and then allow them to pass in the House, even if it means support from only a minority of Republicans. For everything else, however, the House is free to accommodate the crazies, since anything initiated by the House is on the "make a statement" track, not the track that yields legislation signed by the president.
The other one is an update, over at Salon, of my debunking of the theory that Republicans nominate their "next in line" presidential candidate. Basically, most parties most of the time nominate anyone who is an identifiable consensus candidate going into the cycle, but beyond that there's no real indication that Republicans defer to "next in line" candidates.
