Not only is the right mostly mistaken, in my opinion, in their policy prescriptions. They're also at increasing move from reality, in such a way as to preclude even the possibility of consensus, bipartisanship and a common ground.
Listen to Beck, Limbaugh and the rest. Google the 'Cloward-Piven Conspiracy', arising from a 40 year old article in that enormously powerful journalistic institution, the Nation. Consider their insistence that there's more money to be made in accepting anthropogenic global warming than shilling for the largest, most profitable corporations and national sovereign funds ever seen in the known galaxy. Birth certificates. A game I can play all day, this.
And if you call them on this stuff, you're told that Beck, Limbaugh et al. are merely entertainers, and not to be taken seriously. Wildly disingenuous, that, and a bald cognitive dissonance. An inevitable consequence is foreclosure of even an approach to a common ground here: you can't take the Beckerati seriously, but he's telling the truth. Another is that, if they only talk to themselves, they won't ever have the slightest reason to reconsider their views, as, perhaps, incomplete descriptions of reality, subject to error, and not, in and of themselves, sufficient reason to dismiss their opponents as not merely mistaken, but illegitimate, as advocates not merely of different policy prescriptions but of tyranny.
