Yeah, he would move the US closer to that of far more successful countries such as Venezuela. His economic views are not very different from those of Hugo Chávez.
If Americans are keen on standing in line for hours to buy toilet paper, he's their man. If they want to become dramatically poorer due to his protectionism, he's their man. The same goes for Brits and Corbyn.
Of course, the only places where the likes of Sanders and Corbyn stand any chance of winning an election are internet polls on places like CFC. And thank God for that.
You do know how the US government works right? It's not as though the president can just wave a magic wand and make all of his policies law. Unlike most other nations in this world, the US was actually specifically designed to have a weak executive branch so one person could not wield too much political power. So even if Hugo Chavez himself became president of the US, he would not be able to do what he did in Venezuela unless he had the full support of both Congress and the Supreme Court (which he would not).
