But here's what I have:
Senate:
Alaska - The GOP primary was surprisingly close. Have Joe Miller get even more of a boost, and he's surefire going to lose to Begich in November.
Arkansas - Not going to happen. Cotton was a very good candidate.
Colorado - Easy. Udall decides to run more than a one issue campaign. He wins narrowly against Gardner, and FH writers cry everywhere.
Georgia - While Perdue was the Georgian Romney, Kingston was certainly going to be an even worse candidate. He runs a toxic campaign that annoys many Perdue voters who either stay home or vote Nunn. Nunn barely achieves a majority.
Iowa - Bobby Buckley runs a real campaign. Ernst still wins by a close margin.
Kansas - Orman never runs, and Milton Wolf successfully primaries Roberts. Both men run a very vicious campaign, but Taylor is ultimately the narrow victor.
Kentucky - Yeah, no.
Louisiana - The DSCC decides to actually help Landrieu out in the runoff and Cassidy runs a weaker campaign. Cassidy still wins, but by a narrower margin.
Montana - Not going to happen. The Democratic candidate was fantastic (at least in my view

), but Walsh had too much of a sting.
Missisippi - Chris McDaniel prevails, even if the primary goes to a recount. He unfortunately wins, but his presence damages the GOP brand nationwide.
North Carolina - This one is very easy. Hagan's GOTV campaign is more successful, and she wins as expected.
South Dakota - Rick Weiland isn't such a baby, and decides to drop out. Gordon Howie recieves more media attention as a result, and Rounds is flanked by strong challenges from both sides. An aggressive Pressler campaign is barely enough to win. He announces that he will caucus with the Democrats.
West Virginia - lol.
There you go, the structure of the Senate's makeup is now:
49 Democrats
48 Republicans
3 Independents (backing Democrats)
Gubernatorial:
Arkansas - Not going to happen.
Florida - This one's a doozy. Have fangate heat up (no pun intended) more and have Crist step up his campaign earlier. He wins as almost everyone thought he would.
Georgia - Deal's corruption blows up, and Kingston has a negative effect on the Republican ticket. Carter, like Nunn, barely reaches a majority.
Illinois - While it would be easier to just have Quinn (rip in piece) run a better campaign, it'd be more fun for Bill Brady's comeback to actually happen. He gets thrashed by the People's Pat in November.
Kansas - The strip club scandal doesn't emerge, and turnout efforts have better results. Brownback goes down in defeat.
Maryland - Hogan's cancer comes out earlier, and he decides not to run. The GOP nominate some weakling that can't even overcome Brown's non-campaign.
Massachusetts - Baker's campaign is more like his 2010 one. Coakley, despite being Coakley, ekes out a win.
Michigan - The Detroit water crisis hits the rocks even worse than OTL, and Pay to Play causes a few resignations. Schauer narrowly wins against the scandal ridden Snyder administration.
Ohio - Have literally anyone not called Ed FitzGerald run. Kasich still wins, but it's not an embarrasment like OTL.
Wisconsin - Russ Feingold runs, and gives Walker a run for his money.
So now there are:
26 Democrats
23 Republicans
1 Independent (Walker remains unbutterflied)
I can't think of much for the house.
