True, Chiat is a hitman for the left. If the left is starting on Rudy this soon, they are becoming concerned.
Yes. Chait is a hit man -- thoroughly detestable. And this attack on Rudy is thoroughly ideological. Chait is also wrong to assume that "a tough policy against the homeless," as he puts it, tells us nothing about how someone might approach foreign policy. However, he's right to point out that Rudy has few credentials on foreign policy, either in terms of experience or substantive positions. His strong municipal leadership after 9-11, and several tough statements against the terrorists (which would probably have come from almost any NY mayor), are taken as powerful evidence of foreign-policy competence and toughness. And they shouldn't be, even though they're still good things.
I say this as a conservative who leans toward Rudy. But we'll need to see more, and hear more, and learn more about what he has DONE.
