Well, the coalition that could have produced the 413 map - that is, near-Obama margins with minorities, newly liberal suburbs, and a partial WWC rebound - would be pretty hard to beat for a long time. This is the "theoretical coalition" that produced those insane Wisconsin polling mirages in October 2020.
Pretty much. Democrats have a huge coalition on their hands, but their problem is turnout. That can't all be blamed on Republican attacks on voting rights or undemocratic institutions favoring land over people, though- the quality of their nominees is a big reason for this continuing electoral parity that they don't want to accept.
