The details are complicated, but there has been a meme batting about off and on that this Tuesday, January 3, when the new Congress starts, there will be an odd moment when the Senate will have a majority of Democrats due to people leaving and arriving. At that moment, apparenty, Vice President Biden as President of the Senate could make certain motions turning the chair over to the Dem Leader, who could then introduce the nomination of Merrick Garland for the Supreme Court, and they could just pass it. It may be that there is some flaw in this plan and that has been realized. But if there is not and the only thing holding Biden and Schumer and other Senate Dems back from doing this is some sort of sense of propriety and not doing things unusual, I would say to heck with that. The Republicans have broken nearly every rule in the book, including their refusal the whole last year to consider Garland's nomination, which was already unprecedented and effectively breaking the rules.
So, given that this may be the only and last chance to hold off Trump from giving control of SCOTUS to conservatives, and it would be morally justified in that Obama had his right to appoint his pick, I think they should do it if they can. But I have heard nearly no talk in the last few days about this, which makes me suspect that either there is some flaw in the plan or that they are just plain too chicken to do it. If the latter is the case, then no wonder the GOP is just taking over everything. But, who knows, maybe they are plotting it and keeping that quiet and will do it. At least I can hope so for the next two days or so.
