Sanders’ foremost national supporter and surrogate will likely be at home in New York on Monday night, watching the results come in with no small amount of interest.
So what, specifically, will she have her eye on?
"I'm really going to be looking at turnout, but not just turnout numbers -- I'm going to be very interested in Latino turnout; I'm going to be very interested in working class turnout; I'm going to be very interested in youth turnout,” she said. "Those are the three indicators that I'm going to be really looking at because I think that's going to tell us a lot about November. If we get huge turnout on Monday, I'm going to be feeling really good. No matter what happens, no matter what those results are.”
And no, she does not have a “Bernie wins” tweet saved in her drafts.
"Oh, no, I largely don't draft my tweets too far in advance,” she said. “I'm too superstitious for that."
