The animating concept behind the Trump campaign will be chaos. This is what history shows us fascists do when given the chance to participate in democratic political campaigns: They create chaos. They do it because chaos works to their advantage. They revel in it, because they can see how profoundly chaos unnerves democratic-republicans—everyone, that is, whether liberal or conservative, who believes in the basic idea of a representative government that is built around neutral rules. Fascism exists to pulverize neutral rules.
So they campaign with explicit intention to instill a sense of chaos. And then comes the topper: They have the audacity to insist that the only solution to the chaos—that they themselves have either grossly exaggerated or in some cases created!—is to vote for them: “You see, there is nothing but chaos afoot, and only we can restore order!”
The Democrats are actually way more internally organized now. About 30 years ago during the 90s both parties reached almost unanimous internal ideological consensus’ and essentially all vote as a single blocks. The state we’re in now with this polarization is part of this, and an example of the increased factionalization of US politics.
It’s crazy to think how there were staunch segregationist Democrats in to the 70s even as the party as a whole had been (successfully) catering to younger urban demographics that came alongside industrialization. We can’t really imagine something like that occurring now. Even Biden was opposed to bussing and a lot of his “across the aisle” examples even today involve working with segregationist Democrats, not “across the aisle” as we interpret it now.
