"Wouldn't it be better for 2006 if the republicans stand up and vote down an unqualified moderate?"
Of course not! That would be totally demoralizing. Conservatives haven't given up, the Republican leadership has. I will still vote and vote Republican (or Conservative since I'm in NY), but alot of people won't turn out and alot of conservative groups are not going to do their traditional leg-work. You take conservatives for granted to your own demise.
Gee, that sounds vaguely like blackmail.
What good are you if your vote is for sale?
