Why do you think this won't happen? Ginsburg was nominated on June 22, 1993 and confirmed on August 3, 1993. That's 43 days between nomination and confirmation. John Paul Stevens was confirmed in 20 days. O'Connor was confirmed in 2 months. So if we assume September 26th as a nomination day, the Republicans have enough time to confirm someone within the normal timeframes and the normal hearings/debate.
If Trump nominates Barrett today and we use the same 43 days, Barrett would be confirmed on November 8. It'll probably end up happening sooner, but it's not out of the norm.
I am of the camp that McConnell should have at least given Garland an up/down vote. And I think McConnell and the rest are hypocrites given what went down in 2016 versus what's going on now. But Legolas is right - what was extraordinary was what happened in 2016. Not what's happening now.
Senate Schedule is only 8 days till the election unless they change that.

Week 1: Sept 30th, Oct 1st, Oct 2nd
Week 2: 5 days from Oct 5th to 9th.
That is not enough time if you want to do a "normal" process.
Of course this is politics and what is normal is subject to change.
(And this is as it should be. Signed a person who is for Court Packing / Court Reform / Whatever Euphemism you want to use and was also for "Confirm Them" in '04 and '05 with the Blue Slip stuff of that time being nonsense.)
