I'd have to say Krugman is wrong on this one. There has been plenty of substance in the Republican field. The problem is that it's all bad substance.
The frontrunners are all campaigning on a platform of continuing and even expanding upon George W. Bush's policies. Not one of the major candidates will state the plain and obvious truth that George W. Bush has been a horrible president quite possibly the worst ever and as a result we're getting absolutely no real explanations of how they'd repair this mess. And that's the real question people want to see answered, but it can't be answered until we first make that crucial admission.
The only reason to say there's no substance is that it's an act of repression, an emotional defense mechanism against the sheer mess we're seeing. But as you said, Bruce, anybody who knows what to look for can see what their policies would be.
