Science is becoming partisan not just because of funding, but because too many people have stopped trying to persuade the people who need persuading. Instead we get statements like, "It has to do with the disdain that the people currently in power have to live in a shared reality with the rest of the population."

If your starting talking point is that half the country is irrational or detached from reality you've already abandoned the work of building consensus. We can keep doing the "Jon Stewart" thing and scoring points by calling the other side idiots, or we can grow up, act like adults, and do the much harder work of convincing people.
