Except that he is a Democratic candidate, so that means he had to be approved by them as you can't just decide to run under a party's banner, and their lack of comment on this would imply that they're fine with him stabbing other Democrats in the back as a campaign technique rather than running on his merits… Assuming he even has any, frankly I think he sounds like a piece of shit that should've been cut loose the minute he started this shit, he's an embarrassment to the party.
