Yes sir.
If Maffei couldn't beat Walsh in a bad year for Republicans, especially in the NE (when Clinton and Spitzer cleaned up), I don't see when he could beat him.
I will say this, Maffei's campaign wasn't really inspiring and only seemed to turn towards that direction in the last week. Given more time it could have happened.
But the possibility remains we may have reached a minimum on the number of seats for the GOP (under current) lines in Upstate NY...its not really a republican area...more 50-50 or 53-47 republican at best, but that means its gonna be really hard to eliminate every elephant up here.
Losing isn't always that bad. McNerney lost horribly to Pombo 2 years ago in CA-11. As for NY-25, it actually voted for Kerry, so a Presidential year might help the Democrats there.
