Well, then, would you prefer we just don't vote them?
You have two choices; one of them doesn't support conservatism in any way, shape, or form.
Who do you pick?
I'd prefer they think for themselves and do what's best for the conservative cause. So, for example, I will vote for McGavick because he's far preferable to Cantwell. But in CT, I'd vote for Lieberman over Schlesinger. In RI, I'd probably not vote at all for Senate. OTOH, if I thought the Rs were going to lose the Senate unless Chaffee were re-elected, I'd probably vote for that scumbag.
But, typically, you're missing the point. It's entirely reasonable, based on a historical comparison to 92/94 to conclude that losing the House this year could lead to greater gains in '08. I for one don't think the Ds could help themselves, the moonbats have too great an influence.
