Tuesday night's big election news may have been Bill de Blasio's landslide New York City mayoral win, but Fox News Channel also took home a big prize, beating out news cablers CNN and MSNBC in both total viewers and the 25-54 demo.

According to Nielsen, Fox drew in almost 2.9 million viewers and 654,000 in the key demo during the 9 p.m. timeslot -- the highest-rated night in the demo for Megyn Kelly's "The Kelly File" since its October launch.

FNC also ruled for all of primetime, attracting 2,729,000 in total viewers and 593,000 in the demo (more viewers than MSNBC, CNN and HLN combined). Despite spiking from the networks' third-quarter averages in the time period, these numbers are meager compared to presidential election coverage ratings.

CNN was the loser of the night with "Piers Morgan Live," drawing 734,000 total viewers (239,000 in 25-54) and the net reeling in 664,000 (224,000 in 25-54) from 8 to 11. MSNBC's "Rachel Maddow" came in a not-to-close second with 1.267 million in total viewers (313,000 in 25-54) and the net brought in 1.035 million (244,000 in 25-54) in the 8 p.m. slot.
