Indeed we need socialist/communist politicians in this country - look how well it has worked in California and countries like Soviet Union, Nazi Germany, Venezuela, and others.
Street homelessness in tents, cardboard boxes and gulags for you.
The Nazis healthcare system isn't what made them evil. It was because they committed genocide and tried to take over the world.
The Soviet Union wasn't a horrible place to live because of their healthcare system. It was because they were run by an Authoritarian who didn't allow any sort of capitalism.
Venezuela isn't in a crisis because of their healthcare system. They're in a crisis because they have a an authoritarian president who abused his power for political gains at the cost of the people.
Unless you believe Bernie is secretly planning on moving away from Democracy and toward authoritarianism, it doesn't make sense to compare him to all those evil regimes.
I'm not a Bernie bro, btw. I don't know for sure what the best path forward is (and I think anyone who thinks they do isn't looking at things objectively), other than it would involve a balance of Capitalism and Socialist policies.
