Fox News went on the air in October 1996. Since that time, the GOP has won the popular vote for president exactly once: in 2004, by a whopping 2.4 percent. If Hillary Clinton wins in November, as appears likely, the GOP will have lost the popular vote in five of the six presidential elections since Fox broke the liberal media monopoly. In the six presidential elections before Fox, the GOP won four landslides. The reasons for the change are complex, and we certainly shouldn’t overstate the influence of any given media outlet. But prior to 1996, a politician could truly succeed only by going to the American people through the media outlets they actually watched, which encouraged communication that persuaded those who weren’t true believers.
