(CNN) – McCain came in third among Missouri conservatives, so how did he win the state?
His overwhelming support among the state's moderates, even those who are sharply at odds with his positions.
Twenty-three percent of Missouri voters believe abortion should be legal, and they picked McCain 2-to-1 over Romney and Huckabee. And 30 percent are against the war in Iraq and they also picked McCain 2-to-1 over Romney and Huckabee.
McCain, of course has a strong pro-life Senate record, and he has made achieving victory in Iraq his top issue.
