I saw the video on twitter, but I can't seem to find it now. It was a CNN reporter directly quoting the warren campaign as saying the South Carolina primary was "all about blunting Sanders' momentum".
...Oops, I don't think they meant for that to slip out. I mean, yeah, it's political and competitive, but when you're struggling to even get 15%, to refrain from dropping out and say something like this is just suspicious af. It's become very clear that knee-capping the front-runner doesn't bother her at all, and all of the recent back-pedaling to make her seem like a team-player was insincere BS.
