Here's the comment made by @berniesanders:

Another clueless troll who has no clue what he's talking about. In fact, I just removed my votes from @steemsports as I find posting photos of a 16 year old pretty fucking disturbing. Until there's an explanation and at least an apology to the community I will no longer be supporting @steemsports and I sure as shit won't be supporting this bullshit by @walden.

I suggest you read the article and comments to understand the context. Seems that berniesanders is awaiting a response from you before he/she will reconsider his/her decision to stop supporting you.
