Move over, Donald Trump. It's time for the adults to take the stage. The first Democratic primary debate, hosted by CNN and Facebook at the Wynn Las Vegas hotel, begins at 8:30 P.M. Eastern time on Tuesday, October 13. Five Democratic hopefuls will participate: Hillary Clinton, Senator Bernie Sanders, Martin O'Malley, Jim Webb, and Lincoln Chafee. Vice President Joe Biden has not officially declared his candidacy, but a podium will be added for him if he decides to join. Anderson Cooper is moderating, and Dana Bash, Juan Carlos Lopez, and Don Lemon will also be asking questions.

New Republic journalists have been covering the candidates for months (or, in Clinton's case, years). Here is a recommended reading list for each of the presidential hopefuls, in order of their latest poll rankings.
