A woman VP?

As I was watching Y & R today, CBS came in with the report that John McCain had picked his VP. I was a little upset since I wanted to know if Victor was alive, but since I've decided to pick who I would vote for president, by their choice of running mate, I got over it quickly. Then they announced that Sarah Palin, governor of Alaska, was McCain's choice. Who?? From where?? I'm so confused.
As I listened to her speak, many thoughts went through my mind. 1) Wow, she's green (and not environmentally) 2) She seems likable 3) She's going to run around the country campaigning with a 4 month old, with down's--sounds tough 4) Can she really get Hilary supporters?
I think I kind of like her. The problem is the I think part. I really don't know a lot about her and I'm not sure if 2 months of campaigning will give me enough info. To be honest, McCain is pretty old and if he dies in office, is Sarah Palin ready to take over? I don't have enough info yet.
