Paul Krugman's political leanings are clear, but that doesn't stop him from writing well-reasoned, informative pieces about health care, his forte. Here he looks at the likely outcome of McCain's health care plan. Most of his criticisms come late in the op-ed, after he explains McCain and Obama's proposals in plain terms. Good kicker, tying the McCain plan to the credit crisis.

Very clear explanation of how McCain's health care plan could destroy the current system, leaving more people without health care than Obama's plan. I appreciate how clear Krugman's explanation is... after hearing the back and forth on this topic during last night's debate, I was pretty confused about it all.

Krugman offers a brief, but cogent comparison of Obama and McCain's health care reform plans. I found pretty fair, though independent experts are not cited.

If you trust Paul Krugman -- and I do -- then he explains all voters really need to know about the difference between Obama's and McCain's health plans.

While no outside experts are quoted, Mr. Krugman himself is an expert, and all of his statements are consistent with the experts I have read. As a physician, I am, relatively speaking, an expert myself. Mr. Krugman provides an analysis agreed-on by all of the physicians I know.

Mr. Krugman offers a thoughtful, albeit truncated, analysis of McCain's healthcare plan, along with a cogent, scathing critique of it. Agree or disagree with him, Mr. Krugman helps make McCain's plan and its consequences more understandable.
