Basically, I figure that although the general phenomenon of right-wing spewing has done serious damage over the past couple of decades, individual wingnut frothers like O'Reilly and Limbaugh, for all their loathsomeness, have limited influence these days. They draw most of their viewers from the ranks of true believers, so their tirades probably change very few minds. Their audience already agrees with them.
But that's not true of my three choices. Matthews' audience is probably mostly liberal and centrist liberal, and he convinces them that liberal politics is an idiotic clown show. Nancy Grace pulls in all types and turns them into slavering lynch mobs convinced that amendments 4 through 8 of the constitution are mere obsolete technicalities. And the WSJ editorial page is read mostly by business people who initially tend toward the right, but are then converted by the WSJ's patented brew of smarminess and intellectual dishonesty into full-time Hillary-hating, supply-side idolizing, worker-loathing zombie shock troops for movement conservatism.
Of these, by the way, the WSJ editorial page is by far the worst. I'm convinced it's done more real damage to the liberal cause than any other single source of the past quarter century. There's probably a good book in that story somewhere.
Anyway, that's that. I just thought I should probably explain myself.
