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

In this regard, the situation here is very similar though to the situation with legal issues. There are issues of simply how to read statues which are almost completely apolitical and there are areas where the gloves come off, like for constitutional issues. I suspect that you could do the same sort of study as this one but with microecon questions and get a similar result where the economists had less ideological bias for those questions. So the situations seem more similar.
