It doesn't matter if bernie is a socialist. It's high time people understand that socialism isnt the devils calling. There are certain rules and regulations in socialist manifesto that organically puts checks and balances on the system, the economy and democracy. Bernie just wants to implement those systems so the government works for the mass instead of a rich few that happens with an ever progressing technological world and an unchecked capitalism.
Also Hillary can eat a dick. Just another corrupt politician
