Mitch McConnell just slays me. He knocks me out. He throws out jokes when he’s trying to be serious.

Such as when he writes an essay on Politico.com and urges Democrats to stop obstructing Donald Trump’s myriad appointments.

Yep, the Senate’s chief obstructionist masquerading as its majority leader, is scolding Democrats for playing politics.

You can read Sen. McConnell’s essay here.

I want to have my say for just a moment.

Majority Leader McConnell has set a new standard for obstruction. He rolled it out in early 2016 when U.S. Supreme Court Justice Antonin Scalia died suddenly. The president at the time, Barack Obama, was empowered — by the U.S. Constitution — to nominate someone to replace Justice Scalia.

President Obama sought to do so. He nominated federal judge Merrick Garland — a superb jurist, a centrist — to join the SCOTUS.

McConnell’s response? He would not allow Garland to have so much as a Senate Judiciary Committee hearing. He wouldn’t meet with the nominee. He instructed his GOP colleagues to stiff Garland.

In fact, McConnell made clear his intention within hours of Justice Scalia’s death. He said a “lame duck” president shouldn’t be allowed to fulfill his duty. We were going to have an election that year, McConnell said, and we should let the next president fill that vacancy.

It was a tremendous gamble on McConnell’s part. He was hoping for a Republican to be elected president. It turned out to be Donald Trump, who then won the election that November.

So, for McConnell today to excoriate Democrats for “playing politics” with these appointments — in the words of a former boss of mine — is like the Happy Hooker, Xaviera Hollander, lecturing someone on the virtues of chastity.
