Hillary Clinton and Donald Trump will face off in St. Louis this weekend as they attempt to make their cases to the American people about why they are each better suited to be the president of the United States.

The Republican presidential nominee was already facing a defining moment in his campaign following a poorly received opening debate performance on Long Island late last month. Now, as his candidacy seems to be teetering on the brink following the release of a 2005 video that depicted the real estate mogul using graphic language as he describes groping women, Trump needs nothing short of a Hail Mary to revive his hopes of overtaking Hillary Clinton.

It's the second of three presidential debates leading up to the November 8th presidential election.
