It's interesting, their nightly news made it out to sound like Cruz didn't really denounce Trump, and that Preibus gave a statement but declined to do so on camera. I wonder to what extent the former might have done so to later court Trump's voters, and the latter to not alienate them from the party.

eta: actually, they show a clip of Cruz
commending Trump. Wonder if that was the true sentiment or if there was some convenient editing there.
