Should the GOP Senators get started confirming Merrick Garland before the election?

I'm reading "Flake says it might be Garland time" (at Politico). Arizona Senator Jeff Flake is saying that even before election day, perhaps the GOP-controlled Senate should move on confirming Garland. Why not wait until after the election (and avoid the in-your-face lack of confidence in Trump)?

Flake's comments come as the Senate GOP weighs how to deal with a Clinton nomination to the Supreme Court. Senate Majority Leader Mitch McConnell (R-Ky.) has ruled out taking up Garland in the lame duck. But that raises the prospect that Clinton could pick someone other than Garland, whom Republicans once praised as a consensus nominee before rolling out a blockade intended to allow voters to weigh in before the vacancy is filled.

What I read between the lines there is: If they wait until after Clinton wins, to move on Garland is to deprive the President-elect of her choice. And that would be after they said that they needed to hold off on Garland because the American people should have the choice of what sort of Supreme Court we want. If the people decide for Clinton, shouldn't Clinton be the one to make the choice? The GOP Senators have held off, in the hope that the GOP candidate might win and get to make the appointment, but if they think Trump is going to lose, their best option might be to move on Garland while they still have a shred of a chance to act as though they're just doing the normal thing of confirming the President's nominee.
