Here is an outstanding video shot by someone in the crowd at the McCain - Palin rally held in Washington, Pennsylvania yesterday, August 30, 2008. It is one of the best I've seen at really giving a sense of the sights and sounds at a McCain event. You can really sense the enthusiasm there. That is an tangible to McCain's choice of Sarah Palin for VP that cannot really be measured by the polls. Clearly, this selection has energized the base of the GOP, which will translate into a much more powerful "ground game" in the run-up to the election - and for the "get-out-the-vote" efforts on November 4.
