Ben Carson — You have advocated for a flat-tax plan, where all Americans, regardless of wealth, pay 10 percent in income taxes. You also advocate a Constitutional amendment that requires a balanced federal budget. Is this another version of Reagan's trickle-down economics, which ballooned our national debt? And if you plan on cutting services, can you tell us which programs you want to cut?
Why this question: Carson doesn't have a voting history like other candidates, so this question provides a closer look at how a Carson economic policy will look.
Mike Huckabee — You came out in defense of a Kentucky county clerk who defied the law by refusing to issue a same-sex marriage license. Is there a point when it is okay to break the law because of religious beliefs – and if so, where is it?
Why this question? Huckabee is a former Baptist pastor, but if he becomes president, he must convince people that he won't put religion above the law.
Carly Fiorina — Donald Trump has recently attacked your physical appearance. Is there anything you would like to tell him right now?
Why this question? Moderators want a fiery debate, while voters want to see how Fiorina will defend herself – and potentially our country - against threats and bully dictators. This is a legitimate opportunity to ignite the confrontation.
