During the Hillary Primaries I was a big Bernie supporter. I thought his policies were horrific but I was willing to give him my support because I beleived he had integrity.
Then when the superdelegates screwed him over and a very evil lady (Hillary) won I was pissed. But then I saw Bernie support the democratic party and even lend his support to Hilary. To see him support someone so corrupt and guilty of almost constant lying caused me to realize he did not have the integrity I thought he had. In that moment he guaranteed I would always vote against him in any future election.
