Debate: another big draw?

The last presidential debate between Sens. Barack Obama and John McCain drew an audience of 52 million viewers. While that is 17 million fewer than what the vice presidential debate drew last week, that is still a lot of people.

And so, tonight's debate from Nashville, Tenn., ranks as the big TV event of the night. Former NBC anchorman Tom Brokaw will moderate, and the format will be a town hall meeting - a format that could play to the strengths of McCain, according to some analysts.

ABC, NBC, CBS, Fox, CNN, MSNBC, Fox News Channel, Telemundo, BBC-America, PBS and C-SPAN will carry the 90-minute debate, starting at 9 p.m.

A LOCAL WEDDING: The season debut of the Style Network's Whose Wedding Is It Anyway? is set in Baltimore - on the 50-yard line of M&T Bank Stadium. The groom is Baltimore Ravens tight end Daniel Wilcox. The bride is Belize Shauna Chin. And the theme of the wedding is Cinderella. (I did not know there was a football stadium in that fairy tale, but I guess anything is possible with reality TV.)
