Well, if we assume the economy/inflation and immigration were the two hot button support issues for Trump, then again I don't see a tremendous amount of radical leftism in Democratic party leadership that Trump supporters objected to -- it was merely these were issues they (especially independents) didn't feel Biden solved, and/or made worse.
Incidentally we didn't recriminalize shoplifting -- we made penalties for shoplifting harsher. I voted for that. Even my very liberal wife voted for that. It won. Problem solved (maybe).
If it really does come down to social issues (which includes immigration -- the data on what immigrants add to an economy vs. what they subtract is very clear -- but the data on our crappy ability to monitor illegal entry is also clear), then I submit that we go back to a core ideology of Trump/conservative supporters: other people are getting something they didn't get, and they're upset about it.
Side note: some of Musk's fairly sudden support of Trump, I think, is a calculation of self-preservation in this regard -- he'd better join up with MAGA before he (Mr. Electric Car, Mr. Tech Bro, Mr. Immigrant, Mr. Hyper-Rich) becomes the target of MAGA since he has so much others don't.
This is where I begin to have problems -- as we've discussed very often before -- social media have made people more keenly aware of their shortcomings/lack to relative success/lack of fame (Andy Warhol was SO prescient!), and they're angry. And along comes a guy who gives them very convenient targets to blame for why they never lived up to what they could be.
But when we really start breaking down agency issues on a case by case basis, there are places for common ground -- like student loan forgiveness, e.g., where I personally have a real problem -- and places open for respectful discussion -- like DEI issues, where I don't have a problem, but I can absolutely see (and have seen) abuse. Then there's support for LGBTQ+ (especially trans people), where you simply aren't going to shake the deeply held liberal view that there's a ton of prejudice on the right side of the aisle. Yet all these issues seem amalgamated into this similar conservative belief connection -- no one should be entitled to get what I didn't (or couldn't).
Then we have the three hot buttons -- abortion, speech and gun control. Democrats tend to share common sense views on all three. Conservatives tend to be "all or nothing" on them. Not sure how we can't consider conservatives more extremist in this regard.
All this said, Trump won, and won clearly, and the reality is we are all going to have to beat swords into ploughshares if we really want to solve problems. I am hopeful the focus is economic and not social. As I've mentioned, with all the time I've spent in rural farmbelt America, the urban left's understanding of this life is often poor and sometimes callous. Quite frankly, I am exhausted with demonizing, my own included. But I am also very protective of and frightened for my LGBTQ+ kid and the world she'll grow up in.
