To me the aspects of Trumpism less native to his party are:
Anti-intellectualism on steroids
Utter disinterest in winning a fair fight, thus language may be weaponized at all times
One way we may see the latter for years to come is in widespread reflexive complaining about fraudulent election results without evidence. The era of social media is exacerbating this partisanship from what I’m anecdotally observing. There seems to be a divide where anti-intellectualism and its alternatives will continue to feature prominently as well in campaigns, although it plausibly could recede to more typical pre-Trump norms.
Either the GOP just attracts the dumbest fuckers out there or they’re self-aware and simply don’t care, and thus go for the stupid vote since it’s gonna be in the bag. Grenell is the dumbest ambassador I can think of in recent (20 year) history. Takes his entire life for granted, not realizing most of the GOP base views him as subhuman because he likes men and is married to a man. It’s like Blacks and Hispanics who vote GOP and then bitch about being marginalized, 'cause at the end of the day your skin color is or name is what those yutzes will judge you for, not who you voted, which isn’t visible.
Trumpism existed as a way to get the rubes to vote R in every election, this is the first time a candidate has actually gone all out trying to follow through on it once elected.
In our loathing for this guy we neglect his absolute genius for hucksterism. He manipulates people with consumate skill. If he loses in the next election or is impeached i can easily see him rabble-rousing his 30% of the electorate for years. The Republicans havenobody to counter this. (Can you imagineMitch McConnel inspiring anyone?) The Trumpist 30% will always be with us. Sadly, isuspect trump will be too until the maw of hell opens to swallow him.
