A similar thing happened with the Teamsters, though that played out with no endorsement - the leadership wanted to align with the Democrats, as they traditionally have. But the bulk of the members are very much Trumpers. 

As I've noted before, this is all indicative of Trump's primary superpower, that of cleaving the members of any organization from their leadership to throw their fealty to him. Although there's a ton of ground-level shit to worry about under Trump - not least of which being economic mismanagement, loss of civil rights, and the whittling of labor protections and social safety nets - in my wildest 3:00 AM obsessing, I fear some event that will involve enlisted men siding with Trump over military leadership in a precipitous way.

Another thing I realized about Trump recently is that he's sort of an avatar of the internet - he takes in all meaning and converts it to noise. He's obsessed with breaking down any existing institutions and remaking them in his image, and he's convinced a lot of people who will be hurt in the process to support him in that. I think it's because he understands the symbolic meaning of those institutions and intuitively knows how to change the meaning of the symbol in a way that will make his followers applaud when he ultimately destroys columns one through four.

Yep, a lot of double-think went into voting for Tariff man because people were sick of high inflation.
