Eyes turn to Biden, Palin

In a year of record viewing for political coverage, the biggest night of all could be tonight's vice presidential debate in St. Louis between Republican candidate Alaska Gov. Sarah Palin and her Democratic opponent, Sen. Joe Biden.

Friday's debate between Democratic presidential candidate Sen. Barack Obama and his opponent, Sen. John McCain, drew 52 million viewers, I would expect this one to be seen by more than 60 million.

PBS anchorwoman Gwen Ifill will moderate the debate being held at Washington University. It will be carried on ABC, NBC, CBS, PBS, C-SPAN, Fox News, CNN, BBC America and Telemundo. ABC had the largest audience Friday with 11.04 million viewers. (9 p.m.)

TOP GUNN: Tim Gunn's Guide to Style starts a new season on Bravo. The big news: Gunn has a new "fashion accomplice" in Gretta Monahan, owner of Grettacole Spas, Salons and Gretta Luxe Boutiques.

Tonight, Gunn and Monahan transform the very conservative closet of a woman as she prepares to move from Washington to Manhattan.

As much as I hate the way these shows encourage excessive consumption, I have to admit I like Gunn's style. (11 p.m., Bravo) ** 1/2
