Fox Business is hosting a Republican debate tomorrow night. It will feature eight candidates: Donald Trump, Ben Carson, Marco Rubio, Ted Cruz, Jeb Bush, Carly Fiorina, John Kasich, and Rand Paul.

The rest of the candidates will take part in the undercard debate prior to the main event.

These are supposed to be debates on economics, so I’m hoping to hear the candidates asked one question:

“What will you do to address the failures of the Federal Reserve’s zero interest rate policy?”

Ted Cruz gave a great response to this question at the CNBC debate, arguing for sound money “ideally tied to gold.” Now every candidate needs to respond to this issue and explain their position on monetary policy thoroughly.

Our hope is that Fox Business will pass on the political theater and instead enable a substantive discussion on this critical topic.
