::Binarybits, you're using the most narrow possible definition for 'partisan' here: Devoted to or biased in support of a particular party. But every dictionary says partisan also means devoted to or biased in support of a party, group, or cause:  The Discovery Institute is clearly devoted to or biased in support of a particular cause, if not party. Meaning they are still partisan. Sorry, but the reasoning given they aren't, not supporting a particular party, doesn't hold water.
