Bernie Sanders has never accepted a corporate check in his 30+ year long career in politics. That's basically his thing. It's what he has been fighting for all his life.
I knew Bernie banked his campaign off small donors but assumed he might of had a pac or a pac was made by supporters of him. Reading this article it shows that three were unofficial supporting him but he tried to distance himself from them.
I'll look into the link later. I wish Bernie and a few others would just resurrect the Progressive Party and steam roll these two shit parties. I'm ready to see some trust busting.
