Pretty sure the 45 Demorats will vote no to confirming Trumps nominee. There are 2 Independents that caucus with the Demorats. There are 3 questionable(Murkowski, Collins, Romney) Republicans that will likely be turncoats. if so that will be a 50-50 tie and VP Mike Pence will be the tie breaker voting yes, making it 51-50 in favor of Republicans.
We will have to wait and see what the Demorats come up with the delay, distract, and confuse the process. And, I'm sure they will try anything.
