According to Jane's Law:
Jane's Law: The devotees of the party in power are smug and arrogant. The devotees of the party out of power are insane.We can see an example of smugness here. They're assuming that they will be in power forever and that “nationally required science standards” will not be written or rewritten by a Huckabee appointee.
One type of smugness that I recall from the Clinton era (but which I haven't seen yet this time) is the “all-or-nothing” argument: that if we accept anything said by academics or the mainstream media, we must accept all of it. For example, anyone who is skeptical that anthropogenic global warming is some kind of crisis cannot cite weather reports because the weather reports come from the same Establishment. I'm still looking for this.
As for insanity … I'll keep an eye on a few left-wing blogs. I'll assume they'll mention nine out of every five examples of actual insanity.
