Who's moderating the next presidential debate between Hillary Clinton and Donald Trump?

The second presidential debate between Donald Trump and Hillary Clinton will feature not one, but two presidential debate moderators. Anderson Cooper, host of CNN's Anderson Cooper 360, and Martha Raddatz, co-anchor of ABC's This Week, will moderate the town hall style debate on Oct. 9 at Washington University in St. Louis. 

Cooper has not moderated a presidential debate before. In 2012, Raddatz moderated the vice presidential debate, which attracted more than 51 million viewers.

The 2012 town hall debate between Barack Obama and Mitt Romney was a comeback moment for the President. In the first debate, Obama appeared tired and aloof. Romney saw a polling bump after his debate performance was watched by more than 67 million people. 

But in the later town hall debate, moderator Candy Crowley fact-checked Romney and Obama capitalized on the Republican's apparent misstep. Obama led in polling from then on.
