Observation on retaking Congress
For instance. Tommy Thompson has decided not to challenge Feingold, and it appears that rookie (and perceived target) Gillibrand may run (practically) unopposed in New York.
The Republicans are going to have lots of opportunities, Harry Reid, Blanche Lincoln, etc, but to really get the "win" they would need these second tier races, and it would seem that the best candidates doubt their ability to win these races.
