During the long night that was the 2012 Iowa Caucus, Fox News came out on top in the ratings. For the first contest of the 2012 GOP presidential nomination process, FNC averaged 2.6 million Total Viewers in primetime. That’s about what the network does on an average night, but it doubled CNN’s take of 1.3 million (which is about double what CNN does on an average night). FNC also lead in A25-54 viewers averaging 683,988. Among the three cable news channels, Fox News was also the only one to see Total Viewer and A25-54 increases from the 2008 Iowa Caucus, when Democrats and Republicans both had candidates vying for their party’s nomination.
