Did Super Tuesday settle the nominations? This week we explore where the races now stand and have another go at decoding the appeal of Donald Trump, with some help from our friends in the Brooklyn nail bar. Our special guest is Xenia Wickett from the Chatham House think tank. She explains what Trumpism tells us about how America sees its place in the world and what this election might mean for the future of American foreign policy. Plus we revisit Ireland to explore the messy election result there and see what the future might hold for Irish democracy.
