Alan Abramowitz analyzes the incoming House:
[T]he new House of Representatives will be much more conservative and much more ideologically polarized than the old House. The location of the median member will shift from slightly left of center in the 111th Congress to well to the right of center in the 112th Congress due to the replacement of a large number of moderate Democrats with conservative or very conservative Republicans. In addition, the total number of moderates in the House, almost all of whom were Democrats, will shrink from 75 in the old House to 28 in the new House. As a result, the ideological distance between the median Democratic representative and the median Republican representative will increase dramatically.
