...have to have at least one GOP vote on the committee...
I dont think that is correct is it? The Dems have majority status on the committee, so a party line vote would still go to the floor for a final vote, I believe. Grahams vote is irrelevant.
I heard this on a news commentary (I believe on Fox as I don't watch the others). Their point was that under Senate rules the nomination couldn't leave the Judiciary Committee for a floor vote without the "Yes" vote of at least one Republican. The report was slanted about how the departer of Senator Specter from the Republican Party might have cost them the one vote minimum that they needed on the committee. They further stated that it was entirely possible that Lindsey Graham could possibly take his spot as the leading RINO.
