The Cook Report offers this surprising comment on the intensity gap: “If this level remains constant, you can count on the Democratic majority in the House being toast this fall.”

I think we will remember this month as the one where a GOP House went from hard to imagine to quite possible; perhaps future months will make it seem even more likely.

UPDATE: Overnight, the conventional wisdom changes. From FiveThirtyEight.com: “Think others are too conservative on projecting GOP gains. We don’t have a House model yet, but GOP seems as likely as not to take House.”
