My dislike of Sanders has nothing to do with his policies. I was a Warren supporter, after all. It has everything to do with his inability to compromise and his absolutely-second-only-to-Trump AWFUL supporters. I would love for his ideas to become reality, but the problem with that is not only does he ONLY have ideas, he is so damn stubborn that he has to have it EXACTLY as he says or not at all. He would rather let the world burn to the ground than make concessions to make progress towards his ideal policies. It's shortsighted and pretending that he will somehow be able to walk into the Oval Office, snap his fingers and make Medicare for All happen is naive, at best.
It's not that Medicare for All, or some other kind of universal healthcare are impossible, but they aren't going to happen in the way he wants them to. That's just not how politics work.
And I'll spare you another rant about why Bernie Bros are fuck awful.
