The more I think about it, the more persuaded I become that U.S. Senate Majority Leader Mitch McConnell is incapable of doing the job he took an oath to do.

He swore to be faithful to the U.S. Constitution. The nation’s governing document empowers the chief justice of the U.S. Supreme Court to preside over a trial of the president, and that empowerment allows the chief justice to administer an oath to senators who then vow to administer “impartial” justice in determining a president’s guilt or innocence.

Why, then, does Mitch McConnell declare his intention to violate that oath by saying he has no intention of being an “impartial juror” in the upcoming trial of Donald Trump, who’s been impeached by the House of Representatives on charges of abuse of power and obstruction of Congress.

If McConnell will not adhere to the constitutional provisions set forth in the trial, then he needs to recuse himself from the trial itself. He isn’t the only senator who’s vowing to less than impartial. Fellow Republican Sen. Lindsey Graham has declared that he doesn’t need to hear any evidence, that he’s made up his mind that Trump did nothing wrong. Yep, it’s a done deal, says Graham.

To be fair, there likely are some Senate Democrats who also have made up their minds. I do not recall hearing them declare it publicly and brazenly as McConnell and Graham have done. These men’s bias is stated and well-known.

It is amazing in the extreme to hear the Senate majority leader say without hesitation or reservation that he won’t be faithful to the oath that Chief Justice John Roberts will administer to the 100 senators who will act as jurors in the latest trial of the century.

It makes me wonder if the chief justice has any authority to determine whether senators are in contempt of the Constitution.

One can hope …
