COMMENT: By David Von Drehle
With impeachment gathering steam, the fate of President Donald Trump is in the hands of a single institution. Not the Senate, though that's the body established by the Constitution to make the ultimate decision to remove a president. I'm thinking of Fox News.
Ordinarily, I'm skeptical of the power of media organizations - even Fox News. Though it is the most-watched cable (shall we say) "news" channel in the United States, its average primetime viewership of about 2.5 million people is less than 1 percent of the nation. The audiences for MSNBC and CNN are typically even smaller. Most Americans have better things to do with their evenings than to be harangued about politics.
However, those Fox News viewers punch far above their weight in one regard: They are the core of any hard-right primary challenge that might be waged against an incumbent Republican senator. I believe based on conversations with knowledgeable Republicans that Trump is neither popular nor admired among the Senate majority, but he is feared, therefore tolerated. The fear stems from his firm grip on that Fox News-viewing core and the belief that he could turn the core into an incumbent-crushing machine.
To the extent that Trump's grip begins to loosen, the fear will begin to lift and the president's Senate firewall will begin to crumble. That's how I figure it, and I think Trump might be making a similar calculation, because his Twitter feed has been peppered lately with his annoyance at Fox News over various perceived acts of hostility. He might believe that he can maintain his standing solely through his unmediated tweets, regardless of Fox News. But I don't think he really wants to find out.
