The ratings are in from last night, and Sen. Hillary Clinton's first ever appearance on The O'Reilly Factor proved ratings gold for the FNC program. Bill O'Reilly saw his best ratings of the calendar year last night, and at least the best ratings since mid-November 2007.

In the A25-54 demo, O'Reilly's 939,000 viewers put him ahead of the rest of the three networks (CNN, MSNBC and HLN), totaling 768,000 viewers. The 11pmET repeat of The O'Reilly Factor was the second highest rated cable news program in the demo last night.

In Total Viewers, O'Reilly saw 3,664,000 viewers, compared to the three-network total of 2,435,000 viewers.

Part II of the interview, with a focus more on policy, airs tonight.
