"Bernie Sanders is that he is Independent"
Independent people would run as an independent not register as a Democrat when they're not or ever have been a Democrat.
Only if they never wanted to get any media attention at all. Fuck Donald Trump but at the very least he and Bernie have called attention to the fact that two political parties work together in an effort to maintain the illusion of choice while simultaneously trying to control the outcome regardless of what "the people" want.
Coke or Pepsi? Doesn't matter. They are basically the same thing. Imagine a world where you only have two options but either choice leads to the same end point.
I don't think Bernie is a commie. I think Bernie loves the idea of America. I think Bernie loves people.
Trump, like most politicians, just loves himself, money and power.
