There is some truth to this.
However, there are still a lot of Bernie Bros out there RIGHT NOW who are saying "Don't shame me for my choice. The mainstream Dems are EVIL", while at the same time saying that they were too good to vote against Trump just because he was more evil than Hillary. Some of them even seem to imply that he might be LESS evil than she would have been, lol. A lot of those guys got self-righteous, copped a resentment against Hillary and the mainstream Dems, and helped get Shitler the presidency because they couldn't overcome their feelings. Hell, BERNIE HIMSELF told them to vote Hillary after he lost the primary. How could they trust him to be president if they couldn't trust his judgement on that matter?
And, for the record, I was a full-on Bernie supporter/voter. Then, after the primary, I did what the man said and voted for Hillary.
