I think you're going to see two things...
You're going to see the Democratic party largely move back towards the center.
You're also going to see something of a civil war/schism within the Democratic party as the small cadre of hyper liberals attempt to take the party even MORE hyper liberal.
For the past dozen or so years it was the hyper liberal cadre that seized control of the Democratic Party through weaponization of identity politics, criminalization of any small degree of different think, and control of the loud "shout down" demonization politics (you're a Nazi! you're a fascist! you're a homophobe! you're anti XYZPDQ!)
The liberal center thought they would be able to regain control of the hyper liberal cadre when they served their purpose of neutralizing Trump and Maga conservatives. They never saw what the hyper liberal cadre was actually doing -- filling people with disgust and making them either turn even harder to the right or, in numbers that shocked everyone, turn on the left which they had always supported.
It didn't help that the liberal center's responses to legitimate criticisms and fears from the American people -- high prices, high inflation, slipping standards of living, and on and on and on -- were incredibly tone deaf, dismissive, and defeatist.
My biggest fear is that the Democrats get their *expletive deleted*it together in the next four years.
Actually, that's my second biggest fear.
My biggest fear is that the Republicans monumentally *expletive deleted*ck things up once again and hand things to the Democrats on a silver platter.
