I didn't at first include the stuff in parentheses. I added it because of course there is no single explanation for what's gone wrong, and it is going very, very wrong. But this is one important factor.
I'm sure I've remarked on it before, though it would be difficult for me to search out any single post in which I said it: that there is serious reason now to doubt whether a majority of Americans actually want the form of government laid out in our constitution. So I was glad--no, not glad exactly, but interested, and somewhat pleased to see that Trump's recent executive orders caused some to ask the disturbing question:
The first paragraph in that piece contains a link to a more extensive discussion of Trump's orders in particular, and the fact that they are essentially the same sort of thing that Obama did. And that Trump's orders are fine with Trump supporters, and Obama's orders are fine with Obama supporters. It becomes more clear all the time that a great many people, both partisans who just want their side to win by any means necessary, and simpler folk who think the president should rule as a sort of philosopher-king, have no real interest in the whole idea of rule by impersonal law, of a government of laws and not of men, of checks and balances intended to distribute and restrain power.
Benjamin Franklin's famous remark that the Constitutional Convention gave Americans "a republic, if they can keep it" is frequently cited by partisans as a warning against whatever evil they think their enemies are up to. But at this point it's applicable to the people at large. It's questionable whether they even want a republic.
