I think that one of the western NY Republicans who barely managed to win this time will be defeated.
Only one that's possible is Walsh. I'm still wondering how Kuhl was even vulnerable, that's a very safe Republican district, even in a year like that. And Reynolds was only vulnerable because of Foley, he also has a very solidly Republican district (not all that conservative, but quite Republican)
Walsh on the other hand, is probably done if he faces a rather strong candidate. Maffei wasn't all that great.Kuhl performed rather weakly in his initial election with only 51%, though a Conservative Party candidate siphoned off 6%. Reynolds also was held to 55% in 2004 by Jack Davis. I don't know why these two didn't perform as they should prior to 2006, though.
