The past decade or so in our politics has been marked by one thing more than any: division, polarization, tribalism. Whichever word you want to use to describe it. Who is our friend, who is our enemy and where our outrage comes from has come to define political life. In his new book, author and columnist George Will tackles this and other phenomena seen over the past 13 years. George Will joins Cheddar Politics to discuss "American Happiness and Discontents: The Unruly Torrent, 2008 to 2020."
