Republicans generally don’t know how to play hardball, but if they did, they would have at least two members indicate they were going to oppose the nomination right up to the day of the vote. This would put great pressure on the democrats to all vote no in order to have a victory. After all votes are cast, but before the vote is announced, the two republicans could change their vote. The nomination would be confirmed and the swing state democrats would be on the hook for opposing him.
That would be a sneaky underhanded trick. I think I like it.
