Just a reminder: with all this talk of Republicans taking back the House of Representatives and winning back some Senate seats this fall, don't forget the other, possibly bigger, consequence of the 2010 elections. Redistricting.
The statehouses will provide the third leg of the Republicans' 2010 victory. We have long suggested the GOP would gain a net +6 governorships. We now believe they will win +8. This boon to the GOP for redistricting will be enhanced by a gain of perhaps 300 to 500 seats in the state legislatures, and the addition of Republican control in 8 to 12 legislative chambers around the country.Republicans are likely or even certain to gain the governorships in Iowa, Kansas, Michigan, Oklahoma, Pennsylvania, Tennessee, Wisconsin, and Wyoming. We believe the GOP candidates also have an edge in Illinois and Oregon--both of these quite surprising. Democrats will also pick up a few statehouses to cut their losses: Hawaii is near-certain, with fair to good shots in Connecticut, Minnesota, and Rhode Island (though we currently retain the last two as toss-ups).
