There is no Biden rule.  There was a Biden speech under different circumstances that did NOT recommend what the Republicans actually did (not hold hearings).  

Biden's floor speech was on June 25, 1992, more than three months later in the election cycle.

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 (hence there is no Biden rule).

He didn't argue for a delay until the next president began his term, as McConnell actually did. He said the nomination process should be put off until after the election, which was on Nov. 3, 1992.

Oh, and just to keep up, we Americans are going to have to pay for the wall, Trump has no replacement for Obamacare, Trump is using an unsecured phone, and not just giving speeches to Goldman Sachs people, he is putting them in charge.  There's more but you get the idea.
