Rich, Joshua Kurlantzick has an interesting cover story (sub. req’d.) in the New Republic on this topic. It nicely captures some of the Republican divisions on foreign policy. But I do have a few reservations.

1) Sam Brownback’s presidential campaign is viewed “as a long shot” by more than just “some Republican analysts,” and the idea that he “could win backing from American Jewish groups for his staunch support of Israel” seems even more far-fetched.

2) While I would be delighted for Jon Kyl to be president, I don’t think of him as a “potential presidential candidate.” My guess is that he will again support John McCain in 2008. The notion that Kyl is a crypto-protectionist is also dubious. Kurlantzick contrasts Kyl to Frist, noting that the Cato Institute classifies the latter as a “free trader” on its scorecard. But Cato also classifies Kyl as a free trader. Kyl actually outscores Frist on this front for the most recent Congress Cato has rated.
