Because of the DINO's, Lieberman, and others.
The other thing is that the D's aren't going to want tit for tat. They stonewall Bush's picks, the same is going to happen 'when' a D wins the WH.
God help them if either Akaka or Inouye kick it in Hawaii.
I couldn't disagree with you more. The Dim's don't care about the future - they plan on being in power forever, and they have already shown they can obstruct as a minority. They have the LSM in their pockets to obscure and lie for them.
Secondly, Lieberman and other DINOs are all pro-choice, so there's no help on conservative judges there. Lieberman voted against the partial birth abortion ban, after all. You'll only get DINO votes for a stealth candidate, and then we won't know whether that stealth candidate will become another Souter.
