If this nomination fails, Bush, Rove and the GOP will see how much they stand to lose by not appointing a verifiable, Scalia-like justice. The Republicans are in deep trouble if they alienate their base on this issue and the appointed of a known originalist is the only thing that will motive the base.

The problem I see with "verifiable" is that it translates into "Borkable" by the Dems and their RINO allies.
