Well, it’s possible that McConnell is just dying (his health has been poor for a long time now), but also, the impossibility of his job has been made clear. He’s dead to the Trump Republicans, he’s unable to deal with the House GOP (for reason #1), and the Democrats absolutely loathe him. He’s a power broker without any power; he’d be screwed regardless of who wins the presidency this year. The last several years have been a humiliation for him — nothing better is on the horizon.
