A majority of Congress are politicians, but not necessarily educated conservatives.
Actually, I think most people in the U.S. are conservative, they just don't think of themselves that way. So why aren't Republican Congressmen real conservatives? I think it is because they actually believe the BS coming from the MSM about conservatives being "out of the mainstream" or some such, therefore they would like to be seen as "moderate". But we know from experience that moderates have, by definition, conceded the argument before it has even started. (Meeting the Liberals "half way" from a position of starting at the halfway point.)
And since you apparently don't read The New American, may I suggest you give it a try?
These are too reasonable for DG, I'm afraid...
