Bernie Sanders and Elizabeth Warren are in the middle of a bitter feud.
The media says the feud is about Bernie Sanders and sexist remarks he made to Warren.
It was seen as a response to talking points for Sanders volunteers characterizing Warren as elitist.
Warren snubbing Sanders handshake at Tuesday night’s debate seemed to inflame tensions even more.
What is this feud really about?
According to Nate Silver, the battle between the two is really over who has the Progressive movement.
