Toward the end of the debate, Warren joined the others on the stage, except Sanders, in pledging to use the Democratic National Convention’s rules to pick the nominee. She would not abide by Sanders’s request to give the nomination to whichever candidate has the most delegates even if that candidate is short of the required 1,991 to win the nomination outright.
This very well may be Warren’s play at the nomination.
Warren’s rally in Washington suggests she’s looking at the long-game and likely won’t ditch the campaign after Super Tuesday. There’s a growing belief that the Democratic convention will be brokered, with Sanders with a clear delegate lead but not able to win outright. And while Bloomberg is quietly navigating his brokered convention strategy, Warren appears to be setting herself up as the compromise candidate.
