Tonight the Republican candidates for president of the United States square off once again in the art of debate. The main event, which begins at 9PM ET on Fox Business, will feature Donald Trump, Ted Cruz, Marco Rubio, Ben Carson, Jeb Bush, John Kasich and Chris Christie. If you're one of those fancy cord-cutters, you can tune it at FOXBusiness.com for a live stream. Unlike some previous debates, this evening's event will not focus on particular topic. Instead it'll cover a number of subjects in the realm of economic, domestic and international policy.
