Vox reports: Fox News is, by far, America’s dominant TV news channel; in the second quarter of 2017, Fox posted 2.35 million total viewers in primetime versus 1.64 million for MSNBC and 1.06 million for CNN. Given that Fox was founded by a longtime Republican Party operative and has almost exclusively hired conservative commentators, talk radio hosts, and the like to host its shows, it would stand to reason that its dominance on basic cable could influence how Americans vote, perhaps even tipping elections.

A new study in the American Economic Review (the discipline’s flagship journal), with an intriguing and persuasive methodology, finds exactly that. Emory University political scientist Gregory Martin and Stanford economist Ali Yurukoglu estimate that watching Fox News directly causes a substantial rightward shift in viewers’ attitudes, which translates into a significantly greater willingness to vote for Republican candidates.

They estimate that if Fox News hadn’t existed, the Republican presidential candidate’s share of the two-party vote would have been 3.59 points lower in 2004 and 6.34 points lower in 2008.

For context, that would’ve made John Kerry the 2004 popular vote winner, and turned Barack Obama’s 2008 victory into a landslide where he got 60 percent of the two-party vote.

“There is a non-trivial amount of uncertainty” about those estimates, Yurukoglu cautions. “I personally don’t think it’s totally implausible, but it is higher than I would have guessed prior to the research.” And even if the effect were half as large as estimated, that’d still mean that Fox News is having a very real, sizable effect on elections.
