You can listen to Biden in 1992, here, when he said Bush should refrain from nominating anyone if a vacancy occurred on the Supreme Court in that election year.
Biden also said the Senate should refrain from holding hearings on any nominee if Bush happened to nominate anyone anyway against this advice.
Well, fellow Democrat Obama ignored the Biden Rule in 2016, an election year, by nominating Garland, which goes little remarked.
But even more little remarked is that the Republican McConnell acted in agreement with the rule in 2016, and refused to conduct hearings on Obama's nominee.
The Executive and the Legislative act as they please in these matters, as is their right. They make their own rules, no matter how much the partisans of this world may try to constrain them.
Elections have consequences.
