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.
Heath Schuler, for one, is a pro-lifer. I seem to remember two other's were as well.
The interesting thing about this is they have 49 plus 2 caucausers. The R's are in no mood for disloyalty, and we only need a couple more. McCain is running for President - no way he goes off the reservation, or its retirement time for the old hob.
Specter may try to drift, and the two nutjobs you site are certainly possibilities.
