Grayson travels through the swing state of Wisconsin in the American Midwest - a predominantly white and predominantly rural location, and one of the states that gave President Trump his victory in 2016. He finds a state that is increasingly bitterly divided over identity politics and hot-button cultural issues like abortion and vaccination. Why are these `culture wars" happening, asks Grayson, and what might help to overcome the divisions? To conclude the series, Grayson makes a map of the American culture wars, one which has strong implications for our own cultural and political divisions in the UK
