“think Murkowski and Collins are the ones who are holding this up. Unfortunately, they control the swing votes. Without them, he is probably not confirmable.”
Murkowski and Collins need to told unambiguously that they will be removed from all Senate committees, no money allocated to their pet projects in their states in spending bills while they are in office, and that no party money will be spent on the reelection campaigns.
The most effective thing would be for their own constituents to confront them. If you live in either Alaska or Maine, make your opinion known.
