The Dems just don't get it and the Socialists get it and cannot get elected if running under their own banner.
The current Democratic Party electorate is made up primarily of elderly centrists. That's going to be changing over the next decade or two. AOC and her squad were all re-elected...dozens of socialist candidates were elected to state and local office in this election. I see no reason not to be pleased with the direction socialism is taking in the US.
The takeover of the Democratic Party is underway and thriving.
