What happened to bipartisanship, Mr. Majority Leader?

Hey, hold on a minute. Maybe for two or three.

U.S. Senate Majority Leader Mitch McConnell pledged to work toward a more “bipartisan” atmosphere in the Senate. So, what does Mr. Bipartisan do? He blocked a “bipartisan” bill that seeks to protect special counsel Robert Mueller from the whims and foolish acts of a president under siege.

McConnell said the bill is not necessary. Why? Because he takes Donald Trump at his word that the president won’t fire Mueller, who’s up to his eyeballs investigating whether the Trump campaign colluded with Russian operatives who attacked our electoral system in 2016.

Yes, McConnell believes the president. He takes him at his word. He says that, by golly, if the president pledges something that he’s true to his word.

Is the majority leader serious? Has he swilled one mouthful too many of the Trump Kool-Aid?

Well, it appears that not all GOP senators are on board. Lame-duck Sen. Jeff Flake of Arizona has promised to block every judicial appointment that comes to the Senate for as long as he continues to serve in that congressional chamber.

McConnell’s pledge to seek a more bipartisan approach — which seemed hollow when he made it — now has been exposed as just another political platitude.

Imagine that.
