There are two essential solutions to this glorious query.
First and most clearly, about half of the U.S. citizens helps Donald Trump as our subsequent president. At a minimal, meaning anti-intellectualism and the rejection of science in policymaking. This is applicable particularly to environmentalism; specifically, these voters consider that local weather change is a hoax, that local weather scientists are bilking taxpayers, and that efforts on this house are engineered to weaken U.S. capitalism.
Secondly, by advantage of the recognition of Trump/MAGA, the Democrats need to watch out to not go too far to the left. There’s primarily zero demand for a candidate like Elizabeth Warren, Chris Murphy, Jeff Merkley, Cory Booker, Pete Buttigieg, or every other progressive.
