No, he was but one of the many careerists who received funds from Russia.
Oh, this old canard again... The DNC lost a few state rep seats, some mayor offices and the rest were city councils. Every bit of that occurred in solid red states. In other words, fake news.
No, he would not have won, you just can't wrap your mind around that fact that so many people legit can't stand him. I mean he's not worse than the average Democrat, but people just can't stand that he acts like he is. There was no cheating going on. The DNC has its bylaws and they blocked him because he isn't really a democrat. That's not cheating, that's exactly how they run their party. His histrionic little whiney white male supporters just couldn't stand it so they fractured the party, handing the gov't to the other (far worse) party.
Maybe Bernie should have run as an independent if he's as popular as you say and if he really wanted to be president instead of just destroying the only party that could have kept Trump from office.
You know, the guy who you think is "the best thing that ever happened for the left in your lifetime". Yeah, that catastrophe...
