And Senate Republicans have openly asked judges to resign so they can be replaced by conservative judges, and their justification for why it's okay to do this so close to an election but it wasn't okay to confirm Garland so close to an election literally amounts to "Obama's a Democrat, Trump's a Republican."
The next time the Democrats control the Senate and the Republicans the whitehouse, I wouldn't expect them be interested in confirming any judges right before a Presidential election either.
It's worse than that. There were at least three high ranking Republican Senators who said that if Clinton won the election, they would go her entire 4 (or 8) years without confirming any Supreme Court nominees, keeping any vacant seats open until there was a Republican President again to fill them.
But when you're looking at electoral math that says you're about to have even odds of taking the whitehouse and probably won't lose the Senate, that doesn't really apply.
