Do Senate Majority Leader Mitch McConnell and Individual 1 care at all about a truly bipartisan achievement that's within their grasp this lame-duck session? By all accounts, no.
A criminal justice reform bill is within reach in the Senate, but McConnell doesn't want to bring it to the floor, and despite his endorsement of it, Trump doesn't care enough to lean on McConnell to make it happen. Or he's too distracted by the impending doom Robert Mueller poses, his overriding obsession of the border wall, or whatever thing is going on in his head that makes him wander away in the middle of something important happening. Trump endorsed the bipartisan legislation last month at the urging of his son-in-law Jared Kushner, apparently to please Ivanka or something, because after a tweet or two, he let it go. Two of the sources Politico spoke with for their article say that his endorsement was a way to distract from the massive loss of the House majority, not because he gives a damn.
For McConnell's part, he doesn't give a damn that it's bipartisan. He won't do it if there are any Republicans opposed, and there are. Never mind that there's very likely a majority of senators in favor, including the chairman of the Judiciary Committee, Sen. Chuck Grassley. He's been trying to egg Trump on to pressure McConnell to do the bill. "We don't have to rely just upon the Republican leadership whip check," he said, implying that McConnell is the main hold up. "And it looks very good to the White House."
But McConnell wants his judges—which he can easily do next year with his larger majority—and getting the government funded. Trump wants his wall. There's not going to be any room for anything else in either of their heads for the immediate future.
