I'm expecting some glowing generalities on behalf of Alaska's Governor, and some intricate policy-speak and definitive hand-gestures on behalf of Senator Biden this evening. The foreign policy segments should be the most entertaining.
If you get nervous watching the debates (like I do), you may want to construct a handy play-along card similar to this one I found...
In all seriousness, I don't necessarily expect the debate to be a landslide. Newscasting and beauty pageantry will prepare a person well to convey to people that you understand an issue without actually substantively answering the question.
While I'll likely be screaming at the tv, "What the F is she talking about, someone please call her on that BS...!" there's a good chance many people will connect with her on a See-that-she's-not-as-stupid-as-people-think-blah-blah-blah-sexism-blah-blah-blah-just-like-me Level.
On the other hand, I have seen her interviews...
Maybe, I'll just put my money on "Gee" for the win.
