The left dominates the media, the universities, Hollywood, the arts, all the engines and apparatuses of communication and creation of culture. Jonathan Chait, in New York magazine, freely admits what everybody knows, and openly gloats.

You don’t have to be an especially devoted consumer of film or television (I’m not) to detect a pervasive, if not total, liberalism. Americans for Responsible Television and Christian Leaders for Responsible Television would be flipping out over the modern family in Modern Family, not to mention the girls of Girls and the gays of Glee, except that those groups went defunct long ago. The liberal analysis of the economic crisis—that unregulated finance took wild gambles—has been widely reflected, even blatantly so, in movies like Margin Call, Too Big to Fail, and the Wall Street sequel. The conservative view that all blame lies with regulations forcing banks to lend to poor people has not, except perhaps in the amateur-hour production of Atlas Shrugged. The muscular Rambo patriotism that briefly surged in the eighties, and seemed poised to return after 9/11, has disappeared. In its place we have series like Homeland, which probes the moral complexities of a terrorist’s worldview, and action stars like Jason Bourne, whose enemies are not just foreign baddies but also paranoid Dick Cheney figures. The conservative denial of climate change, and the low opinion of environmentalism that accompanies it, stands in contrast to cautionary end-times tales like Ice Age 2: The Meltdown and the tree-hugging mysticism of Avatar. The decade has also seen a revival of political films and shows, from the Aaron Sorkin oeuvre through Veep and The Campaign, both of which cast oilmen as the heavies. Even The Muppets features an evil oil driller stereotypically named “Tex Richman.”

In short, the world of popular culture increasingly reflects a shared reality in which the Republican Party is either absent or anathema. That shared reality is the cultural assumptions, in particular, of the younger voters whose support has become the bedrock of the Democratic Party. …

[The] capacity to mold the moral premises of large segments of the public, and especially the youngest and most impressionable elements, may or may not be unfair. What it is undoubtedly is a source of cultural (and hence political) power. Liberals like to believe that our strength derives solely from the natural concordance of the people, that we represent what most Americans believe, or would believe if not for the distorting rightward pull of Fox News and the Koch brothers and the rest. Conservatives surely do benefit from these outposts of power, and most would rather indulge their own populist fantasies than admit it. But they do have a point about one thing: We liberals owe not a small measure of our success to the propaganda campaign of a tiny, disproportionately influential cultural elite.
