Video shows Sarah Palin heartily endorsing the Bridge to Nowhere and congressional earmarks for Alaska

So, basically, she's a liar for standing up in front of the American people, every single day, and saying that she was opposed to the Bridge to Nowhere (she wasn't), and that she opposed efforts of Alaska's congressional delegation to get pork for the state through earmarks (she didn't). Josh Marshall spliced together several videos of Sarah Palin supporting both the bridge and the earmarks. She's a liar. Why would McCain pick someone like this? (Because he caved to the religious right.) Why would McCain approve of his campaign repeatedly lying about facts that are already well established? (Because he doesn't think media has the backbone to call him on it.) Does McCain even know what his own campaign is doing any more?
