In this case, you are assuming power they don't have. And, yes, that's letting the media pick our candidate.
They've already tried to destroy Cruz. And, as I've explained, they got it shoved back up their ass. They didn't like it...so they stopped covering him.
But, if Cruz is the candidate, they'll be forced to cover him -- and he'll win again.
Cruz can deal with the media. He can actually make their bias a point in his favor. And he'll gain voters because of it.
And he will gain ground, in particular, among the youth vote (as he already has) because of his anti-establishment views.
I'm supporting Cruz, but would happily vote for Trump -- if he's the candidate. So we can respect each other's views and leave it at that.
I like both and easily support both.
