PPI has been around since 1989 and views itself as Bill Clinton's "idea mill" aka think tank. Why I call them a fossil fuel think tank is detailed here. They oppose climate action, defend fracking, and receive donations from Exxon Mobil.
it's safe to say that their upvotes are farmed, and their organic support is mostly bourgeois economics and political science majors and interns who hope to work for PPI or a similar think tank one day. It's basically a Neera Tanden farm.
