He gets plenty of hate here. I've seen him called a shyster and fraud multiple times.
"multiple times" means more than two basically.
Does he get anywhere near the level of Tulsi Gabbard?
Also if as you claimed the fact that she endorsed Sanders is literally the ONLY reason anyone bashes her then why do I hate her and bash her when I supported Sanders?
The question was does Sanders get as much hate on this board, and the answer is an unequivocal yes, it's only balanced by the fact that he has more supporters.
And yes, even you--someone who allegedly supported Sanders during the primary would likely have nothing to say about Gabbard had she stayed mum and later endorsed Clinton. It's the fact that she left her position in the DNC and endorsed Bernie during the primary, that she received so much attention in the first place.
