You heard more about his shots at the media - you always do - but once he got past that, Trump's CPAC speech was a pretty strong affirmation of his commitment to actually do the things people are getting nervous will not get done.
First let's quickly deal with the media part, though. If you listen to the media itself, you would think Trump is trying to eliminate the free press and silence every journalist in America. In fact, his criticisms of them are very consistent and very specific: He hates their use of anonymous sources, which often leads to stories that are totally inaccurate, and he hates the way they use nonsense angles to make him look bad just for the sake of him looking bad. I think the former is his bigger issue, though, and it's one I've been on the media about for years.
