The Bernie Sanders situation is interesting. I wouldn't count on the idea that he can't win. I thought that, too, but the situation on the ground has made me rethink my position. Bernie is drawing huge crowds, a lot bigger than any other candidate's (including Hillary Clinton). He is raising money at a breathtaking pace, far faster than anyone (including, I think, Bernie Sanders) would have guessed before this all started. He is the most popular American politician online, too. I'm starting to wonder if we're not going to see another election in which a popular wave overtakes Hillary Clinton. Wouldn't that be ironic?
He can't win the primaries though, Democratic party sentiment does not reflect public sentiment.
If it was up to the everyman, he'd have a serious chance. As it stands, Clinton's name has already secured her victory.
