I literally do real stuff in this arena, this isn’t a hypothetical. Money is helpful so of course donors have sway but money is not the only resource. Bernie has sway (used to have more) because lots of people are influenced by him, that’s valuable even if he doesn’t have cash. If you are technically skilled the party has use for you.
Seriously, do you not hear politicians constantly asking people to get involved?
Edit: wait, is this guy ban evading? Economic Education: Get Some!
