Him dropping out wasn’t his biggest mistake. Him choosing to drop out months after the primary process was his biggest downfall. He basically fucked the democratic party because he couldn’t swallow his ego and drop out when it was clear his popularity among the country was dwindling even in the party itself. Every advisor he had said “hey you likely shouldn’t run again” but he stayed, Hell fucking Obama even told him “yo you aren’t going to win this”. His stubbornness to run for a second term is what killed the chances of a democratic win here.

additional note: I don’t blame him though, like I could not imagine working my entire life up to that moment, and then having to say “I wasn’t the change I wanted to be I need to let someone else take the reins”, it must have been such a blow to his self confidence. The fact that he dropped out at all was a show of strength. I don’t think him dropping out at the point he was in changed the outcome overall, the damage in my eyes was done as soon as he decided to continue with the primaries knowing he was losing support
