The Hill citing Nielsen Media Research.
The live event, co-moderated by "Special Report" anchor Bret Baier and "The Story" anchor Martha MacCallum, also delivered 489,000 viewers in the 25- to 54-year-old age bracket that many advertisers cater to.
Sanders, a self-described democratic socialist, provided Fox News with a considerable ratings bump compared to the same day last year. The network saw an increase of 24 percent in total viewers and 40 percent in the 25- to 54-year-old demographic.
Sanders appeared in a town hall on CNN on Feb. 26, delivering 1.4 million total viewers and 551,000 viewers in the 25- to 54-year-old demographic for the network.
Baier and MacCallum were at the top of their game — pressing Sanders on a variety of tough questions and coming back with multiple follow ups, all while keeping the subject matter entertaining.
It's something other Democratic candidates may want to pay attention to. CNN town halls have been a ratings bust. Monday night's spectacle proved that Fox News' audience is hungry for these events and Baier and MacCallum proved themselves more than capable.
