I could find little to support your claim that there were other instances in which the Senate simply refused to vote on a nominee to the Supreme Court. Garland's nomination lasted 293 days until the end of the 114th Congrss.Ok, so thanks for re-doing at least the minimal research.
According to Wikipedia, the last inaction taken by Congress on a SCOTUS nominee occurred in 1853 when the nomination of William Micou was not acted upon due to being late in the Congessional session and Franklin Pierce had already been elected to replace Fillmore as POTUS. Hardly surprising.
Edward Bradford was also nominated in 1852 and the same reason was given for not moving ahead with the nomination.
Finally, in 1845 John Read was nominated for the Supreme Court by John Tyler but his name was withdrawn due to his support of slavery.
Maybe you have other instances that I could not find but from what I found nothing comes close, or recent, to the inaction taken against Garland.
Yes, my comment was supposition but that should not keep one from rendering an opinion. I did. You can, even if it one of disagreement with mine. Originally Posted by SpeedRacerXXX

So like your belief in 2018 being some sort of major "win" and mandate for the Dems(when it was largely run of the mill numbers when it came to actual seat turnover), Garland was simply a victim of politics that had in both action and timeframe applied to other previous nominees.
Kavanaugh on the other hand was savaged with false accusations and largely thrown as hail Mary's at the last minute when they couldn't come up with anything else.
