Tune in to any which one of the networks tonight at 9 p.m. e.s.t. for the world premiere of Vice Presidential Debate 2008, starring Joe Biden and Sarah Palin. (Gwen Ifill guests / moderates in this episode.)

Set at Washington University in St. Louis, the reality show features the two contestants offering their takes on national and world issues. But there’s a catch: one of them will become the next Vice President of the United States of America! Oh snap!

With so much drama in the GOP — McCain is feelin’ the hurt in the typically Republican Indiana, Missouri and North Carolina, and his veep pick now has more than a few chinks in her armor — Palin has to show herself as both more knowledgeable of the issues and a bit more at ease when discussing them. And Biden has to make sure he expresses his views without coming across as some hotheaded, condescending jerk.

Speculation about the program is mixed. Some have expressed disappointment that one of the contestants speaking tonight is all but guaranteed to win the vice presidency prize. (An election episode is schedule to run during November Sweeps.)

But others look forward to the show, many arranging drinking games for tonight’s premiere. There are even Palin Bingo cards out now. (If you want ones for Biden, choose the “Make Your Own” option and cover up the middle space with this.)

Let’s hope this show doesn’t get canned!
