I want to point out something about the bridge to nowhere. I'm probably the only person in the liberal or conservative blogobubbles to point this out, but the bridge actually would go to an airport, so it's technically not "nowhere." The bigger factor that was probably driving the project was that it would have allowed real estate development on the adjoining island to Ketchikan.
Anyway the point of my rant is that Palin was definitely on board with the Bridge to Nowhere, probably because she was getting help from developers and definitely to try to win votes in Ketchican (about 10,000 people). For her to come out now and claim that she had no interest in it is so obviously false.
Here's a good story from AP on the bridge.
