I think you will be surprised at how many of these nominees will be defeated by Republicans voting "nay".

That is always possible. I've been known to become downright incredulous from time to time, jaw dropping gobsmacked.
But if the nominees don't get 50 votes from the Senate, they won't be confirmed, and the president will look a bit foolish for sending the nominee.
My objections are the supermajority requirement, and ducking the vote when given time to consider the nominee.
No way. Maybe 3.
