Future Senate races you're most looking forward to

[Amenhotep Bakari-Sellers]

Also, because 2012 went so well, in the event that Democrats only have a net loss of 2 or 3 seats in 2014 (very possible, especially if we pick up in KY or GA), we could get a fillibuster-proof majority of 60 seats in 2016. Depending on certain retirements, certain candidates who are giving up their seat to run for POTUS, certain possible candidates who could run, and certain incumbents who could be vulnerable, AZ, FL, GA, IA, KY, MO, NH, NC, OH, PA, and WI are all states where Democrats could potentially have pickup opportunities. Certainly, a lot of them would hinge on certain circumstances (i.e. Nixon running in MO, Rubio/Paul/Ayotte being on the national ticket for FL/KY/NH to be competitive, McCain and Grassley retiring for AZ or IA to be competitive, etc etc.)

I don't see the Dems reaching 60 votes and I can see us winning 55 votes in the senate. Best bets are Simon in Illinois, feingold in Wisconsin, and Sestak in Pennsylvania. Maggie Hassen or Tim Ryan can win in Ohio and NH but odds are less than 50/50.

Moderate heroism will not save Kirk or Donnelly. Just ask Scott Brown.

Donnelly is anything but a shoe-in, but look at Evan Bayh.  He was able to serve a term and then get reelected in a landslide in a state that voted for Bush by double digits.  I think Donnelly's chances will largely depend on the climate in 2018.

AZ, FL, GA, IA, KY, MO, NH, NC, OH, PA, and WI

Agreed that Dems have another shot at 60 seats if 2014 goes well. From most likely to go D to least likely to go D, I think I'd go:

Illinois
Iowa (almost falls off the list if Grassley doesn't retire)
Wisconsin
Pennsylvania
New Hampshire
Florida
Kentucky
Ohio
Arizona
Missouri
North Carolina
Indiana
Georgia
Alaska (only if Murkowski isn't in the general election)
South Dakota (only competitive if Thune doesn't run)

Some pretty good targets there, all of which are at least Likely Republican (except for those in parantheses). Lots of first-term senators, many of whom don't have particularly strong approval ratings. Obviously 60 seats is unlikely, but people said the same thing in 2008.

Meanwhile Republicans only really have Nevada and Colorado as obvious targets.
