An update:
Which state house/senates d'yi all think with flip this year?
The National Conference of State Legislatures lists the following top 10 battleground states:
http://www.ncsl.org
Democrats not only picked up the 1 Senate seat, they picked up 5 House seat to take control of both chambers by one vote in each.
Republicans pick up 19 House seats and 3 Senate seats with one still counting. I suspect that their 94R:86D control of the House is a first time since Reconstruction sort of result.
The Republicans picked up 3 seats to take control.
Iowa Not mentioned in the NCSL's list of battleground states, but a 4 seat pickup in the Senate, makes that body a 25:25 split.
The Democrats maintained their one seat majority. In the House, the Republicans picked up 6 seats, to make it 76D:73R:2O.
Minnesota Another state not mentioned in the NCSL list. Democrats pick up 14 seats in the House to make it 68R:66DFL
Democrats pick up 2 seats in the House, with 1 race undecided. If they win that seat it will be a 50D:50R split. But the Democrats also picked up 6 Senate seats to take control there 27D:23R.
Democrats pick up 5 seats to retake control 63D:57R.
Republicans pick up 3 times 3 seats, to assume a 57R:44D majority.
Democrats pick up 3 seats to make it 18D:12R.
Tennessee Republicans pick up 2 seats to take a 17R:16D majority in the Senate.
There are still 7 3rd party members, but the Democrats picked up 14 seats to take a clear 83D:60R:7O majority.
Democrats pick up 1, with a chance for another to take control of the Senate, 25D:23R:1 undecided. They extend their House majority by 3 to 55D:43R.
Incidentally, Washington voters voted for a semi-Louisiana plan for partisan elections. In the primary, candidates from all parties are placed on the same ballot. The two top vote-getters regardless of party will contest the general election. This differs from Louisiana elections where a candidate with a majority is elected without a run-off.
Overall, Dems take control of the lower house in 3 states: Colorado, North Carolina, and Vermont, while the GOP takes control in 3 states: Georgia, Indiana, and Oklahoma. The Iowa House goes from GOP-control to tied.
In the upper houses, Democrats take control in Colorado, Iowa, Montana, and Washington, while the Republicans take control in Tennessee.
