There is no easier way to render a room silent at a social occasion or start an altercation at a family gathering than to praise President Trump or anything he has accomplished — no matter how benign.

In other words, supporting Trump simply isn’t the done thing in polite society. To do so is to risk loss of social status — if not outright ostracism — and open conflict with friends or family. Trump supporters mislead pollsters or simply refuse to answer their questions pursuant to similar psychological and social incentives. All of which leads to a lot of confusion concerning who it is that supports President Trump and precisely why. This, in turn, renders it very difficult for round heel politicians like Joe Biden and Elizabeth Warren to pander to “working class” voters they badly need to “win back” to the Democratic fold in the 2020 election cycle.

Warren will no doubt get her a beer, grab a copy of her DNA test, and seek the advice of the Cherokee tribal elders. Biden, having learned from the media that Trump supporters are all racists, may pour himself two fingers of Scotch and try to imagine what his segregationist mentors James Eastland and Herman Talmadge would do in similar circumstances. In the end, however, it doesn’t really make very much difference. Trump voters all have at least one thing in common. They know that not a single Democrat on that NBC stage Wednesday or Thursday can be trusted — as Talmadge might have put it — in an outhouse with a muzzle on.
