He is taking on income inequality, Citizens United, and climate change.
Income inequality - who gives a shit about what people make except the greedy and the envious? You are not poorer because somebody else is richer. If you want your income to be closer to that of somebody rich then put down your bong and work harder and smarter.
Citizen United - Sanders takes money from the filthy ass union PAC and millionaires so he is a hypocrite. He hates conservatives lobbying but he loves Moon Bat lobbying.
Climate Change - The biggest scam in human history. Only idiots take that scam seriously.
Income inequality is a real problem, look at where productivity is at and where the wages are going, you may want to call those in poverty greedy, which is fine, you hurt your own cause..
Citizens united is a joke, and telling Bernie he gets his money from filthy ass union pacs and millionaires? Yeah, ok, you obviously know all about the tiny amount he gets from unions, and he doesn't run with any millionaires I'm aware of, the majority of his donations are from working class people.
Ah... I suppose the majority of the worlds scientists are idiots. I'm sure you're educated on climate change to talk about as well. Grow up.
