Sen. Warren said she was not going to make an announcement about endorsing another candidate today. "I need some space around this," Warren said, "and I want to take a little time to think a little more." Make of that what you will. But, EVERYONE here should stop assuming she’ll endorse this candidate or that or anyone at all. There is a LOT for her to think about, including whether she wants to continue as a Senator or transition into a role in a Democratic administration.
