The only obvious referent for Trump’s tweet was Ilhan Omar. The other three just kind of piled on. They apparently thought “Anti-American? He must mean me.” And they were, and are, obviously, quite happy to wear that mantle.
And they are now the face of the Democrats. This has been the de facto reality for some time, but it has now become obvious, thanks to a clever trick by Trump, which should have and would have been seen as a trick by mainstream Democrats in any era before now. But they couldn’t help themselves. Their passions are too strong, their lunacy too embedded.
Trump will win easily in 2020, if we can avoid massive fraud, and prevent the media monopolies from the successful use of mass propaganda.
