But that is how it ends up working, intended or not. The media spending so much time critiquing tweets means less time critiquing policies. And the critiques of the tweets can be very easily dismissed as fluff. Leaving very little observable media criticism of Trump for those who dismiss that stuff out of hand.
It’s also how it worked during the campaign. Nobody knew a single one of his policies, and 46% of the country thought that was a wonderful thing.
