I'll disagree here to the extent that there's a difference between a self-serving campaign brochure sent from an individual politician, and an official press release sent from the office of governor.
There's a range of publicity and marketing and advertisement in all these things certainly, but in this specific case - as Montgomery pointed out - there was nothing in the press release to which all that anti-DEI, anti-CRT sentiment was attached.
No news event. It was only anti-CRT and anti-DEI sentiment, and was untethered from anything newsworthy or actionable.
It was an anti-diversity tract alone.
So to me it exists outside the normative range of public relations. Even political public relations.
It's not just another version of brand enhancement. The character of propaganda is not only to misinform and mislead, but to prioritize unthinking emotion (usually hate and / or fear) above information.
