Tonight the citizens of New Hampshire will make their voices heard when they cast their votes in the first true primary of the season.
Then, on Thursday at 9pm ET, Hillary and Bernie will take the stage in Milwaukee, Wisconsin for a debate hosted by PBS News Hour. You'll be able to watch it on your local PBS station, as well as at PBS.org and on YouTube.
Saturday night, there will be a number of rematches to watch for when the Republicans get together in South Carolina. Will Jeb Bush continue to have success against Donald Trump? Will Chris Christie keep making Marco Rubio look foolish? Will Ben Carson successfully find his way to the podium? All these questions and more will be answered at 9pm ET on Saturday. You can catch the debate on you local CBS affiliate, www.cbsnews.com or in the CBSN app on your Roku, Apple TV, Android TV, iOS or Android device.
