People are sick of the anti-Trump media.
Over-the-top anti-Trump media combined with the tax cut.
For the first six months I think Americans sort of looked at Trump and half listened to the media trying to discern if there was any veracity to their howling that he was a deranged madman. I believe Americans have come, or are coming, to the conclusion that the corrupt media is just a shrill, vile megaphone. In fact, there is some evidence that seems to point that Americans in large measure are turning off the media due to the overload of incessant barrage of negative hate-Trump spew.
My never-Trump sister even remarked that the stupid media is "making it just too obvious" that they plain hate the guy. I was floored.
And just sick of the media. The worst in the last few days was the Washington Times hit piece on Billy Graham, and the CNN townhall whereby the NRA spokeswomen basically had to be escorted out for fear of her life.
