And who was the nominee who was prevented from getting a hearing?

From your article:

There was no Supreme Court vacancy to fill.

There was no nominee to consider.

The Senate never took a vote to adopt a rule to delay consideration of a nominee until after the election.

Nonetheless, Biden took to the floor in a speech addressing the Senate president to urge delay if a vacancy did appear. But he didn't argue for a delay until the next president began his term, as McConnell is doing. He said the nomination process should be put off until after the election, which was on Nov. 3, 1992.

Big differnce between the two.  Shame you can't see the differences.
