At the heart the MAGA project is about White Christian Nationalism. I really do NOT want to use that term pejoratively but it encompasses the central issue of a reactionist attack against 4 big trends in the first quarter of the 21st century
1) Global populations being much more mobile (aka immigration waves),
2) Global populations being less Christian (a shrinking demographic compared to the other great monothestic religions of the world and increasing agnostic viewsin the west),
3) People being much more relativist in their moral thinking about issues such as sexuality and personal morality (gay marriage and trends toward legalization of drugs).
4) Globalization of trade and the death of distance putting an every increasing number of people into the jungle of the global economy.
BI OT is taken up with ENDLESS discussions about these topics and their subtopics but if one where going to describe MAGA how the movement is a reaction to these four trends feels like a very good starting point. I think also that these 4 trends are "indisputable" facts on the ground. And I explicitly framed them in a morally neutral way.
So if I had a political movement around reversing those 4 trends I got a platform to communicate. I don't necessarily need to be internally logical (I don't think Trump and Maga are) - but I can easily point to one of those 4 things individually and say "bad".
Now dumb politics is fighting your opponent on their turf. So the democrats do NOT need to say they are FOR those four things. But what we have, near as I can tell, is a party who is mostly about defending (and modestly expanding) the core structure of the new deal. Better SS. Better Medicare. Decreasing the cost of Student loans. Maybe some modest expansion of the R&D system in the US. These are not the stuff of passionate voter engagement.
When the democrats DO go big (see AOC, Bernie or Planter) they lack a coherent narrative. We ARE living in a true new Gilded Age but (at least 2 date) no one has constructed a narrative that helps connect that concentration of wealth to diminished economic prospects. I can vilify the great robber barons who were squeezing the grange or killing union organizers. It is hard to point out how Zuck or Bazos are hurting ordinary people (I think they are but it is a really hard narrative in the 21st century to spell out quickly).
It is I think why I am in a down mood today. The four forces laid out above are NOT changing. In a real sense MAGA are the political luddites of the 21st century. But railing against them makes for good voter mobilization. The left needs something similar to emotionally connect.
PS. And a ton of BI'ers are guilty of this. Good politics for MAGA is railing against these four things and then universally saying "And the democracts (in other words 50+ million people) are universally FOR it. Thus "We are for strong borders and the rule of law and (all) democrats are one worlders that would do away with citizenship and let every Mexican national come into the US to work at any wage they wanted." "MAGA believes that there is good in Christianity and (all) Democrats believe in paganism and want us all to follow shiria law")
