"great works of fiction" - very clever comment on "the dismal science". It's true that Krugman's commentary is increasingly about social policy, which revolves around economics. Furthermore, economic policy is politically partisan, though it shouldn't be.

Doctor K (I like that!) got his Nobel for quantitative macroeconomics, which involved a lot of formulas. I'm not too bad at math, but I'm not going to wade into those equations. I like the general insights.
