The scariest story of the day is this one in which a political scientist runs the numbers and determines that the new congress is going to be batshit insane. (And it's based on the conservatism of the GOP before the Tea Party takeover!)
The 112th House is likely to be a good deal more conservative than the Newt Gingrich-led House of 1995-97. In the Gingrich House, moderate Republicans actually outnumbered very conservative Republicans by a wide margin. In the 112th House, however, very conservative Republicans will greatly outnumber moderate Republicans. Whereas moderate Republicans held the balance of power in the Gingrich House, they will have almost no influence in the 112th House.
