I can see a compromise that should be acceptable to both sides
1- Obama makes his nomination
2- The Senate agrees to hold hearings on the nominee
3- Committee hearings are scheduled begin the week after the elections and last for two days.
4-Both sides agree not to filibuster said nominee or the Senate changes its rules to limit debate in this one instance.
5- Senate promises and up-or down vote
6-Obama promises not to withdraw the nomination
This can be easily done prior to the end of the Congressional session, ,it would have nearly two months to get it done ( from Nov 8-Jan 1) but could be done in a few days.
If Hillary wins, then the Senate votes on the “ moderate” Obama nominee before she takes power.
If the GOP wins, even if Trump wins, they can vote Obama’s nominee down and allow the next president to make his selection.
I like this sandbagging approach and thought about it myself even prior to reading your post.
