The race for the 25-54 demographic -- the one that networks like MSNBC really care about -- is up for grabs and totally variable during the 8pm hour, as last week's data demonstrates. Of course O'Reilly is clearly #1, but the other channels are fighting for #2 on any given night. The four numbers are Monday through Thursday's averages, in thousands:

FNC: 512, 422, 445, 382

MSNBC: 148, 131, 107, 158

CNN: 154, 99, 125, 198

CNBC: 201, 26, 122, 70

HLN: 89, 109, 174, 146
