Science is partisan, at least the 'science' being addressed in this article, because the funding for this science comes from a finite source and there are competing demands placed on this finite source. As any competent scientist knows, taking something from a finite source leaves less in the source. There are differing ideas and beliefs, some partisan (including those of the esteemed Mr. Colbert), on how best to divide up this finite source.

Certainly most universities now have a very strong liberal bias. I think most science departments were left leaning in the 1950s, but it is stronger now. (I think colleges and universities have always been more progressive than the general populous.) The administrations of universities are now very strongly Democrat leaning. I think that Trump just sees a lot of Democrat run institutions and thinks, "Why should the government support these institutions run almost entirely by Democrats."

Both sides have biases against parts of science:
