At this point, the goal is to normalize the rhetoric. He's been very effective at being able to downplay things by having said them for years. We know his playbook; he's continuing to follow it.

CNN is covering it this evening, along with some of his other recent announcements (which amount to rounding up his political enemies & millions more besides), but infuriatingly still downplaying what his vision entails, nor how popular that is with Republican voters.

Trump's latest comments about "vermin," "retribution," "day-one dictator," and "poisoning the blood" have hit Associated Press, NPR, Reuters, and BBC, who have responded matter-of-factly by comparing to it to the rhetoric of Nazis and Mussolini. Mein Kampf got name-dropped more than once.

I am also seeing coverage from CNN, ABC, USNews, USAToday, and NBCNews.

Now, which media you consider mainstream, and what kind of coverage you consider adequate can change the answer. I don't know what they're saying on TV, for example. But when even Forbes runs a front-page article which compares Trump's rhetoric to Hitler's in the first paragraph, I'd say there's no lack of mainstream coverage, and they're not dancing around the issue anymore.
