The Future of the GOP

If the Reagan era is long over, and if the Tea Party has had its day, the makeup of a post-Trump Republican Party, as well as the broader conservative movement, remains unclear. Princeton historian Sean Wilentz, author of 'The Age of Reagan: A History 1974-2008' says Trump and the current GOP share important similarities but also differ sharply from the party during the Reagan era -- and that makes predicting the future impossible.
