His point was that the WH and Senate shouldn't contemplate a SCOTUS nominee in an election year if they are controlled by opposite parties. Not hypocritical as that's not the case this time.

Also:
1. Don't impeach a president in an election year.
2. If dems wanted their adversaries to respect unwritten norms, maybe they should have refrained from baselessly accusing the nominees of gang rape (Justice Kavanaugh, Clarence Thomas).
3. A SC Judge vote needs BOTH WH and Senate. That was not the case in 2016 regardless of who said what. That is the case this time. It's the President's prerogative to nominate, and the Senate's prerogative to confirm.
4. This time, it would also most likely be a contested election. So not having a full supreme count will be a disaster.
Btw, I am NOT a fan of McConnell. But this case is very different.
