Let me make a confession. I have no idea who the Democratic nominee will be in 2020. Nor am I completely sure, since we are being honest, who the Republican nominee will be. (Trump, I guess?) McConnell’s decision to cut off Warren may have been a disaster of epic proportions for the GOP. Or it could have been a brilliant strategic move, elevating an unlikable Massachusetts liberal to the top of her party. McConnell himself is probably ambivalent.

I do suspect, however, that if Harry Reid had cut off Ted Cruz’s microphone in 2013 the Nevada Democrat would have been hailed as a hero and genius. Even so: The shoe-on-the-other-foot argument may not count for much any more. Nothing may count for much any more. If the last year and a half has taught us anything, it is that what we think is supposed to happen does not. Brexit was not supposed to happen. Trump was not supposed to happen. The Patriots’ comeback was not supposed to happen. Yet here we are.

And no one seems to be drawing lessons from any of this. I open Twitter and see the very people who were convinced Trump wouldn’t win the Republican nomination, who were convinced he’d lose the general election, immediately embrace the most negative interpretation of anything Trump says or does, of any event that might impact him in the slightest. They may well be right. But they just as easily may be wrong, as they have been, consistently, for some time. A modicum of humility and skepticism would go a long way. I understand that these qualities are not especially useful in a city of careerists and poseurs and pseuds. But why not give them a whirl nonetheless.
