I have been reading a surprisingly good book by Sam Rosenfeld, The Polarizers. A phrase from it explains precisely how Biden won the nomination: “non-ideological patronage organizations.” In short, these are organizations that can deliver bloc votes, originally ethnic, now religious, or civil society. The DNC cultivated churches and neighborhood organizations for decades, gracing them with $1,000 there, $5,000 here. Then it was time to call in the chips, and these areas all miraculously turned out for Biden. There was no air left in the room for Sanders, Warren, or anyone else. It was retail politics at its rock-bottom — no adroit trickery — and it worked. Now we’ve got someone two answers away from Trump on the cognitive function test, and we’re going to have to work that much harder to dig ourselves out.
