. . . and the Booman suspects he knows why (emphasis added):
Jonathan Chait wants to know why it is suddenly so popular for Republicans to tell the public that they are not scientists and therefore are unqualified to have an opinion about whether or not climate change is actually occurring. It’s because they lack even an iota of moral courage. It’s because they are paid liars. This is not complicated and it shouldn’t even be debatable. Outside of a very small handful of genuine dunces who actually managed to get elected despite having personal beliefs about science that would make John Calvin blush, every single Republican who is either denying climate change or saying that they can’t make up their mind about it is actually just being dishonest. For money and career.
