Reps will control OK, TN, PA and IN after the '10 election, and maybe OH. Move Colorado to split. Perhaps MN and NH too.
Dems control RI, ME, CT, MA and it matters not one bit. Nothing to lose in those states for Republicans. WV and AR law prohibits county spliting, so no gerrymandering there. Dems cannot possibly squeeze another seat from NC, they are already overrepresented there.
Republicans have an even money bet on split control with increased legislature representation in ME and it would matter if they made CD2 (i think its 2) more republican and Pingree's district more democratic. NH is going to be difficult because Lynch is on the ticket, but it can be done if they win the state legislature. Republicans are likely to sweep the senate race and the two house races there. Dems have a slight chance of having some authority in AZ if Goddard wins and picks the "independent commission" - I think that will be a big win because we are getting 2 seats next apportionment.
