Democratic U.S. presidential candidates Hillary Clinton and Bernie Sanders are scheduled to take the stage at back-to-back MSNBC-televised town halls in Philadelphia Monday evening, just a day before Pennsylvania voters head to the polls. As in past town halls, both candidates will answer questions by the moderators as well as by prospective voters in the audience.

Sanders’ hourlong session will be hosted by MSNBC host Chris Hayes, beginning at 8 p.m. EDT. Rachel Maddow will moderate an hourlong session with Clinton immediately afterward, starting at 9 p.m. EDT. Live streams of both town hall events can be viewed by clicking here or by watching below.

Pennsylvania is among five states with presidential primary elections Tuesday, along with Connecticut, Delaware, Maryland and Rhode Island. Excluding superdelegates, Clinton has a comfortable lead with 1,428 delegates, while Sanders has 1,153 delegates.

According to opinion polling, Clinton is projected to do well Tuesday. Sanders’ best chance is in Rhode Island. There are a combined 384 delegates at stake for Democrats Tuesday. Many in the party will be watching Pennsylvania, with 210 delegates, and Maryland, with 118 delegates.

Sanders’ campaign is hoping more victories will help the candidate regain momentum. Although the U.S. senator from Vermont was widely viewed as an unlikely presidential nominee at the beginning of his campaign, he has done much better than many initially anticipated, gaining a great deal of support by young people. However, Clinton has built a formidable reputation based on her lengthy résumé, encompassing a stint as U.S. secretary of state, and her fluency on an array of issues.

On the Republican side, billionaire businessman Donald Trump is favored to win the presidential-nominating contests Tuesday. Known for his controversial attacks on opponents and others, Trump has secured 845 delegates. U.S. Sen. Ted Cruz of Texas has 559 delegates, while Ohio Gov. John Kasich has 148 delegates. Like Sanders, neither Cruz nor Kasich has expressed any intention to drop out of the White House race.
