Can Herman Cain go the distance with no experience leading government?

Herman Cain has rocketed up the polls with his charismatic personality and catchy 9-9-9 plan, but can he really be the leader of the Unites States with no prior government leadership experience?

David Frum, CNN contributor, discusses Cain's candidacy in his new CNN.com opinion piece, "Why Herman Cain can't be president." Frum argues that Cain's "style is no nonsense, but there is nonsense in the content."

Today on American Morning, Frum talks to Christine Romans about Cain's proposals, explaining why he thinks that his lack of executive governmental experience is a big problem for his campaign.
