Yes, he is.
The media and the electorate today are nowhere near as subtle today as they were in Reagan's day. Ronaldus Magnus taught the media a lesson they never forgot.
Comparing Cruz to Trump in the "media war" is a bolt-action to a battle-rifle.
More like a grenade vs. a firecracker. Nobody compares to Trump’s manipulation of and continuous in-your-face attacks on the media, now or historically.
You seem to think that there is animosity between the Donald and the media. In fact, their relationship is symbiotic, each benefitting the other. The more Trump spews, the more copy for the press. The more copy from the press, the more opportunity for Trump to spew. The media have their candidate. For all their protesting, they know he is pro-choice. They know he can’t do jack about immigration without congress. He can never lead a true conservative groundswell like Cruz can. So congress doesn’t fear him, they welcome him. His business insider schtick is made to order for the crony capitalists in congress. And that includes big media too. Kabuki theater.

The MSM are totally supporting Trump, and attempting to ignore Cruz.
Trump is their guy, as long as they see him blocking Cruz.
