US elections 2008: If John McCain wins the nomination, he shouldn’t put a foreign policy novice like Mike Huckabee a heartbeat away from the presidency

With John McCain’s narrow wins in New Hampshire and South Carolina making him a shaky Republican frontrunner, people have engaged in some absurdly early speculation as to whom he might choose as a running mate. One early favourite is former Arkansas governor Mike Huckabee, the darling of the evangelicals. But if McCain is the man he and his supporters say he is, he won’t do that to the country.

McCain’s official campaign biography says: "As the son and grandson of distinguished Navy admirals, John McCain deeply values duty, honour and service of country." That’s the theme of his campaign. His determination to prove his own integrity inspired his decade-long fight to impose strict new regulations on campaign finance. Told that his support for the Iraq war might doom his presidential candidacy, McCain repeatedly says: "I’d rather lose an election than a war." Newspaper endorsements, like this one from the State in South Carolina, echo those sentiments:

John McCain has shown more clearly than anyone on the American political scene today that he loves his country, and would never mislead or dishonour it. He is almost unique in his determination to do what is right, whatever the cost.
