I think the point was to muddy the waters about Bork getting a fair shake and Garland not. When Bork died is irrelevant, he may very well have retired years before dying, many of them do, so it's pointless to speculate.
Garland did get a fair shake, however.
His name and reputation weren't dragged through the mud, even though he didn't have enough votes to get confirmed.
He didn't have enough votes? How do you know? And why would the Republicans have dragged his reputation through the mud? You basically just said "We treated Garland fairly by holding up his vote for over a year otherwise we would have trashed him".
The Republicans weren't forced to sully his reputation, and didn't. We know nothing about alleged parties that Mr. Garland attended as teenagers, or anything about Garland's sexual history. And that, BTW, is good.
There's no reason to suspect Garland is anything but an upstanding citizen who deserved to be on the Supreme Court.
Had Mrs. Clinton won, he would have been put on the Court.
Maybe, he should have been on the court over a year earlier.
