The New York Times' Ross Douthat does a column that casts some light on what's happening in today's Congressional Republican Party. He observes that the same people who are catering to the Tea Party and its obsession with Obamacare are also the people who are trying to develop new policies for the Party.
Douthat marvels at that, I'm not exactly sure why. Most of the energy in the GOP over the last four years has been Tea Party-driven.
