Some of this is honest stupidity, but most of it is careerism. Pouring scorn on the polls and on unwelcome news reports, predicting a Trump landslide with very little hard evidence to back up that wishful thinking, and, above all, reassuring conservatives that our ideas are more popular than they actually are, that the vast majority of Americans are on our side even if they don’t seem to know it, is a good way to build audience share and a social-media following. And if — as is likely though not certain — this is revealed on Election Day as a fraud and a fantasy, then you can always complain that the election was rigged and that the Deep State has done you wrong. Those doggie vitamins aren’t going to sell themselves.

Good on Williamson to call this out. There is no incentive for media talking heads to tell their audiences what they don't want to hear. We need to make it easier to do the right thing. But how?
