I hope Chafee loses so NRSC money won't be spent for what wouldn't be much of a victory even if they managed to save him. Given that the race would be close, NRSC would probably end up spending a lot of money up there that could be spent elsewhere.
I would vote for Lafey in the primary, and--holding my nose very tightly--vote for Chaf in the general if I had to. Isn't Whitehouse another Kerry, Boxer, etc. type? As bad as Chafee is--and he's plenty bad--he's with us 20% of the time. You gotta do what you gotta do.
