Palin likes to talk about Obama saying one thing when he is talking to people and something else when he is talking about those same people.  (The famous San Francisco speech)
Apparently, John McCain also likes to say different things to different people:

The Royal Gazette (Bermuda) has the video of the new Obama ad. And is promising more of the story tomorrow. I couldn't find any archives on their site, so maybe we will just wait and see. For right now, the main stream media is mostly reporting that McCain was quoted on the floor of the Senate saying the loopholes need to be closed, while in Bermuda he was promising to keep them open. So clutching to loopholes, dollars, guns and religion. Oh here's a link to the Gazette. They had the story on the front page as of right now. I will check back tomorrow. And it will be interesting to hear the response from McCain.
