Indeed we can, and it'll last until somebody says 'abortion' or 'drug legalization' or 'patriot act'. So long as we care more about the things we disagree over than about the importance of agreeing to disagree, conservatives will stay weak.
So far as getting rid of New England's RINOs is concerned, we won't, unless the lot of us vote for the Democrat, no matter how bad. If you say you have to vote for Snowe in 2006, or at least go third party or stay home, then you won't have much of a complaint when you have to vote for Snowe again in 2012.
In the case of Shays, I know for a FACT that there is general disgruntlement with him. Unfortunately I was redistricted out of his district, or I WOULD have run against him.
The Dem would probably have beaten me if I won the primary (which I most definitely could have), but I would have knocked that pompous windbag off.
