Why isn't this man president, no seriously why isn't he president

I don't think there has been a single person in the past eight years, remotely, as qualified as bernie sanders. I've never seen someone fight against the machine nearly as hard as sanders. He has the capability of uniting people on a level far greater than both obama and trump combined. He understands the root cause of so many of the problems in america and realizes that you have to fix the root cause in order to solve issues. And most importantly he cares about people. I know folks that i've met sanders, and said he's one of the kindest human beings they have met. Sanders at age 83 is more eloquent and fierce in his delivery than trump is and iI guarantee he would have Obliterated trump in a debate.
