Sanders is not responsible for the actions of his supporters. And it’s important to note the Bernie Bros do not represent the entirety of Sanders’s base. But this has been a problem for far too long. The vitriolic harassment was present in 2016 when Sanders lost the nomination, and it has become worse this time around.

The duration and frequency of this online harassment suggest this is more than just the angsty musings of a few online trolls. This is a deep-rooted mindset, one that viscerally despises those who oppose the revolution Sanders’s base supports and one that has now worked its way into the heart of Sanders’s campaign.
