Politicians and people who make a hobby of following politics are used to the rhetoric, posturing, and manipulation- it’s part of a game where the pendulum swings back and forth periodically but for the most part things just sort of move along comfortably. Trump sort of throws things off kilter, but then everyone resumes the gamesmanship.
The problem I see is that while people are analyzing the finer points of the game, they’re oblivious to the fact that a new game is being started, and the entrants to the game are not accultured to the rules of civil politicing.
The politicos are in the middle of the street slapping each other with white gloves and trading snide remarks, but the audience on either side of the street isn’t there to listen to the banter. The audience is sharpening its knives and would be happy to dispose of the oblivious gents in the street first so they can get to business.
Bile and hatred has been cultured dr a while on the far right, and while widespread indifference has provided a buffer with the more enraged parts of the left, that buffer of apathy is waining and left-sided anger is rising-fast.
