POTUS pardon of John is a great thing. And good TV.
Trump is the 800 lb. Gorilla in the room when it comes to ability to use media. He also isn't afraid to get a little dirty which is a nice change after all the Republicans trying to play nice with the other side.
But even with all that, this pardon was just a really decent thing to do, and it's moments like this that resonate with people.
