Ahead of Wednesday's GOP debate in Arizona, Columbia Journalism Review editor Michael Hoyt had some advice for moderator John King: Ask the tough questions on foreign policy, national security and the economy rather than simply "Who is more conservative?"

Michael Hoyt is executive editor of the Columbia Journalism Review, where he has written and edited many articles about journalism and its challenges.
