I'm in no position to confirm it because I don't watch that stuff & am TV-illiterate, although I would consider it a very interesting turn of events if true. Not there's not much we can do about this specific instance, but because one could imagine it to be an early-stage experiment in a new level of message coordination for mind control of the masses through repeating their propaganda.
If this sounds like batshit paranoia to anyone, then they may not know who Edward Bernays was, and what he and some of his peers, including Walter Lippman, thought and did. Bernays, the nephew of Sigmund Freud and inventor of modern "public relations"; Lippman, the most-respected editorial voice of the New York Times in the period between the World Wars--Google them.
I certainly do believe that certain privately funded, behind-the-scenes forces in this country could coordinate a collaborative campaign such as you suggest. If they have actually done so, then we are going to be in for a total barrage of coordinated messaging from here on out.
Certainly the labor unions are the most significant source of funds for the Democratic Party, have been a thorn in the side of organized criminals in the suites, and just generally piss off the.001% They are the single biggest source of opposition to the Upper Crust on their path to perfecting of a Randian hell-world. They would be the logical first target.
But hardly the only target. Social Security. ACA. Medicare
in whatever order they choose.
