We have been flooded by retirement and recruitment news since the beginning of the year, as incumbents and potential candidates had time to ponder their next move during the holiday season. This seems like a good time to assemble as exhaustive as possible a database of all the politicians we are keeping an eye on for Senate races: Which Senators are being closely monitored, and what potential challengers could emerge?
Retirements
Five Senators are already known to be leaving their seat open in 2010: Kansas’s Brownback, Florida’s Martinez, Missouri’s Bond, Ohio’s Voinovich and Delaware’s Kaufman. At least 12 other Senators are on the retirement list:
| Those we are watching closely | Iowa’s Chuck Grassley Texas’s Kay Bailey Hutchison |
| Those whose retirement would be unexpected but plausible | Illinois’s Roland Burris Oklahoma’s Tom Coburn New Hampshire’s Judd Gregg Arizona’s John McCain Alabama’s Richard Shelby Pennsylvania’s Arlen Specter Louisiana’s David Vitter |
| Those no one trusts * | Kentucky’s Jim Bunning Hawaii’s Daniel Inouye Maryland’s Barbara Mikulski |
[*Inouye, Mikulski and Bunning both announced they would run for re-election in December, but it will take much more for them to be taken off retirement watch given their age and health problems. Don't forget that as long as a congressman has not decided for sure to retire, he rarely admit to be even thinking about it or it will be impossible for him to prepare a re-election campaign, hire staff and find donors.]
There are only three Democrats on this list (Burris, Mikulski and Inouye, the first of which is not even a Senator yet), versus nine Republicans. And that only adds up to the unbalance of the Senators who have already announced their retirement (four Republicans, one Democrat).
Recruitment
Over the past week, we were treated to Jeb Bush and Chris Matthews’s decisions to pass on the Florida and Pennsylvania Senate races, respectively. But we are only getting started, and there are many more people to watch! The problem that could soon arise for Republicans is a vicious circle in which a wave of retirement and recruitment failures leads to more retirements and to more potentially top-tier challengers passing on a run.
I have written in bold the names that attract the most speculation. And this is a work in progress: I have most certainly forgotten many people and I will add any names that I might have forgotten. (You can also check my newly created recruitment page).

It’s former Treasurer Richard Moore in NC, not Attorney General.
Nice new design too!
The Dmes have a very deep bench in North Carolina. Easley is very unlikely to run, since Schumer tried to get him in 2008 against Dole and he said he did not want to become a senator becuase there were too many meetings!
Hey, Taniel.
What’s with calling the Lt. Governors like Carney and Mitch Landrieu, Lt. Generals?
As to Louisiana, Jay Dardenne is a Republican (which isn’t to say he couldn’t still run against Vitter).
Interesting General/Governor slip - it’s been corrected, as have Moore’s titles and Dardenne’s party. Thanks!
For Washington, you mean Murray rather than Leahy. Also Davis, In Alabama, has an oddly-spelled first name of Artur (rather than Arthur). But that’s a pretty minor booboo.
Interesting that nobody is listed as a prospect for the Maryland Senate seat. With Sen. Barbara Mikulski likely to run again, that’s just as well.
Even if Mikulski retires, however, a GOP win is a long shot; ex-Gov. Bob Ehrlich seems to me to be the only Republican candidate with a decent chance of winning in an open seat situation (he wouldn’t dislodge Mikulski if he tried) and he seems to have disavowed interest in running, at least so far.
As another Marylander, I agree with the implication of Mike in Maryland that former governor Ehrlich is the only Republican in this state at present who might be a fairly serious statewide candidate. But I’d go so far as to say that he’d be very unlikely to defeat a Democratic Senate nominee even if it wasn’t Mikulski. If she retired, I’m sure that there would be a wild scramble among ambitious Democrats in the September primary. Still, it’s a very Democratic state and seems to be getting moreso all the time.
