some of the well-known ones like vox are definitely very lib but i usually have a pretty fun time watching some of the obscure ones. other channels i know of are defunctland, wendover, oversimplified, philosophy tube... just looking for a bunch of video essays to watch now that school's started and all my friends are away on campus lol
Wendover is incredibly lib but it's also non partisan unlike vox. This sort of academia is fairly lib (i.e. very market and real politik focused), so it's hard to find anything else.
