The major media, who are overwhelmingly supporters of the Democratic Party, believe that Republicans, by and large, are not as smart as Democrats. Republicans are more religious (hence less rational), and have resisted what the Democrats, the left, and the media believe is settled science on a most important subject: that the Earth is on its way to overheating, with catastrophic consequences to follow, due to high carbon dioxide emissions.
It matters not, of course, that the belief in “settled science,” new data be damned (virtually no temperature change in close to 20 years), has made the climate change camp appear in many ways to be behaving like an intolerant religious group themselves. How dare conservatives mock the God of global warming? In particular, the left likes to believe that science in general is a major dividing point between the two political parties.
