In his weekly appearance on NPR’s “All Things Considered,” Brooks said the debate, which will be dedicated to the topic of foreign affairs, is an opportunity for Romney to talk about other issues than the Sept. 11 attack on the U.S. embassy in Libya.

“Don’t nitpick about Benghazi,” Brooks said. “Don’t have a little argument. Show some of your personality with some vision of America. Use foreign policy to expose your character, rather than getting lost in the weeds of some small foreign issue of the past. That would be my advice to both sides.”

Brooks said debates are more about personality than substance.

“People are not voting on your foreign policy,” he continued. “They’re voting on your personality, so you better expose that through a foreign policy vision.”
