Is a man who is just discovering the Internet qualified to lead a restoration of America’s economic and educational infrastructures? Is the leader of a virtually all-white political party America’s best salesman and moral avatar in the age of globalization? Does a bellicose Vietnam veteran who rushed to hitch his star to the self-immolating overreaches of Ahmad Chalabi, Pervez Musharraf and Mikheil Saakashvili have the judgment to keep America safe?

A bridge to the more polarizing global politics of the 20th Century? Or a man with more caution, steadiness and pragmatism? That’s the choice.
