Doesn't matter. The dems will hold out for the next Congress in the hope of picking up seats. Their base will demand it. They will listen to their base. The RINO negotiators will keep their word and oppose changing the rules of the senate. No vote on SCOTUS nominee this Congress.
Polls on Lou Dobbs tonight suggest that the Dems will pick up seats as many people are unhappy with the RINOs.
How? This would be a vacancy in the highest court of the land. There is no justification for delay.
