But beyond that, the modern G.O.P. is no home for people who believe in objectivity. One striking feature of surveys of academic partisanship is the overwhelming Democratic lean in hard sciences like biology and chemistry; but is that really hard to understand when Republicans reject science on so many fronts?
One recent study marvels that even finance departments are mainly Democratic. Indeed, you might expect finance professors, some of whom do lucrative consulting for Wall Street, to be pretty conservative. But even they are repelled by a party committed to zombie economics.
Which brings me back to General Milley. The U.S. military has traditionally leaned Republican, but the modern officer corps is highly educated, open-minded and, dare I say it, even a bit intellectual — because those are attributes that help win wars.
Unfortunately, they are also attributes the modern G.O.P. finds intolerable.
So something like the attack on Milley was inevitable. Right-wingers have gone all in on ignorance, so they were bound to come into conflict with every institution — including the U.S. military — that is trying to cultivate knowledge.
