Conservative David Brooks thinks so (via Crooks and Liars).

BROOKS: Right. There’s the war. There’s really a torpor in the administration. They’re not doing anything right now. I think it’s now likely to move the House—that they will lose the House. And I think House Republicans, privately, most of them admit that. For like a year they were saying, “Well, we’ve got it so sewed up with redistricting. We’ll lose, but we won’t lose the whole House.” I’d say about two weeks ago the conventional wisdom shifted and people said, “We’re in such trouble. We are going to lose the House.”
