As CNN broke away from the solemnity of Beau Biden’s funeral with promos for itself and the grab of a few advertising dollars, Fox News — yes, conservative, right-leaning Fox News — stayed focused on a time of mourning for all. Beau Biden wasn’t a Democrat or liberal cause. He was an American, a son, a father, a brother, who went to Iraq and tried to serve his country. Fox got this. CNN didn’t.
