Jonathan Chait says what needs to be said about the bizarre Giuliani-as-foreign-policy-expert meme:
he normal rule in American politics is that if you run for president and your experience comes at the state level, most people will assume that foreign policy is your weak point. You can overcome that political vulnerability–as George W. Bush, Bill Clinton, and other governors did while getting elected. One would presume that this applies even more to presidential candidates whose highest office reached is mayor. And yet we have the strange case of Rudolph Giuliani.
Giuliani’s presidential campaign is starting to win a cult following among conservatives. It’s not his position on domestic policy that’s doing it–he has nothing to say about that. Lord knows it’s not his social issue positions, which even his strongest backers acknowledge are his political weak point. No, he has somehow built a record as a foreign policy guru despite having no experience beyond the municipal level.
