Team Cruz was pushing the Carson is out thing an hour and a half after Carson had already repudiated.
Problem with that argument is that CNN did not tell anyone Carson had repudiated for hours after that. The CNN reporter who was sending out tweets clarified things immediately, but there's no evidence any of Cruz's people were following his tweets; they were following the broadcast news. Tweets going out to fewer than 31,000 people are pretty ineffective when the broadcast has reached millions.
In fact, Carson's comments were explicitly picked up by the MSM denying that he was leaving, and even the original report nowhere claimed that Carson was dropping out.
