She made it absolutely clear that Trump is unacceptable as president. I don't imagine that there is a large subset of voters who would support Warren, then vote for Trump. Maybe the stay-at-home, to-hell-with-it-all subset is larger, but Warren is going to be on the campaign trail through November, attacking Trump.

She even posted on Twitter: "I called out @realDonaldTrump on Tuesday. 45 million saw it. He's so confident about his "counter punch" he waited until Friday night. Lame."
