Bernie team has failed him in so many ways. I truly think he could have been at the top of the polls if he had a better team around him. Why would you have a 77/78 year old man doing 4/5 rallies a day

. Why wouldn’t you pull back before a national debate

Because of that schedule his voice was all fukked up during a major debate. I think the YouTube left and his team overestimated his support and popularity. TYT was using the talking point that he was the most popular politician in the country. It is a difference between people saying they have a favorable opinions of you and actually supporting you as a candidate.
His team should of been better prepared for questions about reparations. Imo they thought they had the nomination on lock and missed several blind spots. With that said, if his campaign swallows some pride and change a few things, I think he still have a chance to win.
