Reading this thread so far (as much as I can) makes me think of Rupert Murdoch who makes his money by polarising people and politics in the countries he operates in, he's been doing that in Australia, the UK and the US for decades, and it shows in this discussion. All very vehement and opposite points of view. Not too many calls for unity here! All about dumping on the perceived enemy.
I think it's true that middle America has become less prosperous over the past 40 years, and it really hasn't mattered all that much whether Democrats or Republicans have been the ones in power, middle America has been in a long, slow decline and no doubt is very pissed off, heralding the rise of blow-hards and conmen like Trump.
In his first presidency, Trump tried to kill Obama-care (and with it the health cover of millions, making the US even more of a high achiever among developed countries in NOT covering its population, nothing to be proud of in my opinion). He actually succeeded in giving generous tax cuts to the very wealthy but not, of course, to the people who really needed them. If he's elected, Project 25 looks like it will continue in that grand tradition of screwing middle America and any unfortunate who's tainted with the progressive brush, lower in the eyes of some of the readership here, than the lowest form of vermin. Thanks, Rupert! You've made the world a worse, more dangerous place.
I'm not an American, but if I were, voting for Trump and JD would be so clearly to my disadvantage that I can only marvel at the people who would. Unless of course, I was Elon Musk or any of his ilk (spoiler: I'm not); even before the election Trump is already doing the bidding of Musk. Electric cars NO GOOD are now electric cars GREAT. So we already know who's calling the shots when it comes to the real decisions, not the decisions about trans, not about abortions, not about the B**S*** the rich used to distract others from what's really at stake here – the big decisions about who gets how much share of the national pie, and it won't be the MAGA crowd who'll be voting for him, it'll be corporates and the very rich.
