"Microeconomics is obviously nonpartisan, because microeconomics is almost completely apolitical. The gloves come off with macro."

Not really

Price fixing... pigovian taxation.... sales taxes > income taxes.... zoning laws... free trade... licensing regulations... immigration.... lots of political issues where economists agree on a great deal because of microecon

Krugman and Delong are much more combative than the typical economist. You'll get a very skewed picture if you only read Krugman and the people Krugman links to. He's in the public eye so that tends to have, I think, a very negative impact on his popular writing.
