I believe you are spot on.
Sean should have told Graham that we know that each will get an up or down vote on the floor as per the agreement but that doesn't mean that the Reps didn't make a deal to vote against them. Graham himself said it's the vote on the nominee that counts. That's were the deals were made.
Watch the 7 dwarves: they'll kill the rest of the nominees either in committee or on the floor.
Get the dwarfs off the committees. Problem solved.
