Independence Front - I"m quite certain they are. The other day I saw these horrible, hateful and false tweets about Tulsi from a HRC supporter. So I was curious and I checked when he started making the anti-Tulsi tweets -- it was 2 days after she resigned the DNC and endorsed Bernie. Definitely not a coincidence, especially given that David Brock's Clinton PAC has allotted a million for online trolling of anyone who questions Clinton.
