Guest blogger Gina: Political junkies are frothing at the mouth over tonight's must-see vice presidential debate. If you don't eat, breathe and sweat politics, here's a breakdown of what to expect when Republican Sarah Palin gets in the ring with Democrat Joe Biden.

This is a do or die debate for the Alaskan Governor who has lost serious street cred with her conservative base. Palin's embarrassing blunders on primetime have made her look like the village idiot. When CBS News anchor Katie Couric asked how living in Alaska gives her foreign policy credentials, Palin answered, "Well, it certainly does because our -- our next door neighbors are foreign countries. They're in the state that I am the executive of. And they're in Russia..." Another brain fart like this could be the last nail in the coffin for the moose-hunting mom.
She needs to up her game, prove she can think on her feet and give answers that won't serve up more red meat to the ravenous haters.

Joe "shoot from the hip" Biden also needs to hit it out of the ballpark. His off-the-cuff comments on the campaign trail have sparked some cringe-worthy moments. Biden seems confused by his own message, criticizing Obama's recent ad criticizing McCain. The Delaware Senator will try to show he's a straight shooter from a blue collar, Catholic family.  He'll also harp on his foreign policy experience. Going mano-a-mano with a woman raises the stakes in a race that's already hyper sensitive to any signs of sexism. Biden must show Palin some R-E-S-P-E-C-T or he'll get raked over the coals.

Tonight's 90-minute face-off starts at 9 PM ET.
