And mark my words, Trump will start reaching out to Bernie's supporters once Sanders is thoroughly eliminated from the campaign. Go lurk over at DU for a bit. They're pissed. They feel the game is rigged against them and view Hillary Clinton with the same contempt that we had for Jeb Bush. The only difference is that Bush was never the frontrunner.
I remember Ralph Nader, and he undoubtedly spared us from a Gore presidency; hard-core Dems couldn’t convince his young supporters they were throwing away their votes, and Nader himself egged them on by saying Gore & Bush were basically the same.
