Fox News is more powerful than we thought

The article linked to in the second tweet states:

“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. ”
