Amie Parnes from The Hill and author of the #1 New York Times bestseller "Shattered" speaks about the 2020 campaign. Parnes discusses how Joe Biden is bouncing back from an "underwhelming" first debate performance but also how Elizabeth Warren is running a very smart campaign which may cause problems for Biden early next year. With a "top five" slate of candidates in place, who have been the surprises and disappointments? I also offer my predictions for the end of July debates.
