> But they are just opinions.

I largely agree with your post, but it is worth remember that a large amount of effort has gone into painting Krugman as a liberal commentator.

He is also was an individual recipient of a Nobel (*Memorial*) Prize in Economics, was a long time professor at MIT (where he did his graduate work) and Princeton. His published work is important in multiple areas of economics. He has focused on economic crises and his currency crisis work is one of his most important contributions.

I don't think it's entirely appropriate to discuss his thoughts through a political lens. He has been one of the world's foremost experts in this technical area of currency crises. One shouldn't disagree with him lightly on economic topics.
