Does Sanders Have a Ceiling on His Support?

Nate Silver: “I shudder to ask the question in part because of bad memories from four years ago, when theories about Donald Trump having a ceiling were a big reason that people like me initially dismissed his chances in the primaries.”

“In Trump’s case, though, there was at least some polling-driven evidence of a ceiling. He tended to lose ground in polls that asked about hypothetical head-to-head matchups against other Republicans, for instance. And his favorability ratings among Republican voters were quite low for someone who was leading the field.”

“There isn’t much evidence of this for Sanders. On the contrary, his favorability ratings are roughly as good as any other Democrat’s — and often the best in the field, depending on which poll you look at.”
