After a week of west coast tapings of The Factor, Bill O'Reilly finishes up with an appearance on The Tonight Show.

It was right around this time last year that O'Reilly last appeared on the Late Show with David Letterman (probably for the last time). Tonight's interview should go more smoothly.

> Update: During the segment, O'Reilly and Leno talked entirely about the 2008 Presidential race, including the McCain/NYTimes story and the Obama/Clinton "popularity contest," as O'Reilly called it. The Factor host also took a swipe at ...wait for it... not Keith Olbermann, but David Letterman: "So it's a popularity contest, Jay. It's like you and Letterman. They like you better, okay?," said O'Reilly to applause.
