Ezra Klein suspects that Huntsman's anti-war message will draw support:
Is he likely to win? Nope. But he’s even less likely to win if he tries to run the same candidacy that everyone else is running. By staking out foreign-policy territory when no one else seems particularly interested in the topic, he sets himself up to capitalize on a black-swan crisis that unexpectedly makes foreign policy issue #1 in the presidential campaign, and he also makes himself strong on a set of issues where the other candidates understand themselves to be weak, which increases his value as a potential vice-presidential candidate.
