I said this elsewhere, but I may as well say it again:
BB is only left from within the frame of pre-Trump pseudodemocratic American politics. The liberals of the Democratic Party are not left wing, and never have been. Liberalism is a center-right ideology; if you are a capitalist, you are not left wing.
On a less distorted political scale, BB is decidedly centrist. Cory seems to be the leftmost edge of the hosts, and he appears to be a fairly mild DemSoc.
There are a spattering of anarchists and socialists amongst the commentariat, but most range from SocDem to Conservative (by which I mean actual Conservatives, not GOP reactionaries).
We used to have a few more radical types, but a lot of those have dropped off the web to concentrate on the street.
