>b-b-b-but what about all the working class people he's bringing into the process
This is the mentality of the "ivory tower socialist" who has never actually gone out and talked to working class people.
There's this myth among Sanderistas of a vast progressive non-voting majority, but it's plainly false. Most non-voters are (small-c) conservative, even deeply conservative. Nixon wasn't bullshitting when he spoke of the silent majority.
Non-voters aren't all destitute poverty-stricken single mothers and homeless people. A lot of them — even the majority — are just "normies", people who don't give a shit either way, in a large part because their place in the world is fairly comfortable and secure.
Solf libertarians, Chad socialites, self-employed tradesmen, or just general lumpens. These people are the reserve army for a fascist reaction, not the working class waiting to be organized.
