Unfortunately, Bernie will not be the one to lead that. Social Democrats fundamentally have to side with and cater to the bourgeoisie as they depend on Capitalism, unless you mean to advocate for a real revolutionary Socialist party. In the latter case, PSL already exists, and the DSA has powerful Marxist caucuses like Red Star and MUG that are close to gaining over 50% control of the party. I wrote an introductory reading list for Marxism if that appeals to you or anyone else.
