I would not regress too heavily on the Obama-McCain race. I recall Michael Barone saying there were a lot of areas that ordinarily vote Republican that voted for Obama.
House Republicans in ‘10 took 56%, and that’s not even counting the 24th (Marchant was unopposed).
For the TX State Representatives in ‘10, the count was 57% R. 25 Seats, 17-8 R. Average population of the 8 Dem seats: 148059. Average population of the 17 R seats 167282.
Iowa is done. Latham and King are in the new 4th, but Latham is moving to challenge Boswell in the 3rd. Braley and Loebsack are in the new 1st, but Loebsack is moving to the empty 2nd.
UT - there’s probably no way to make a mistake here. It’s been impossible to unseat Matheson so maybe the best thing to do is to put him in a Salt Lake City district. Then Bishop in the northern exurbs, and Chaffetz in the southern exurbs. The new district could be the majority of the outstate, but even that one would have to borrow some from at least one of the 4 most populous counties.
