I highly recommend checking out the website Map the Candidates. Although still in its nascent form, the website does a fantastic job of visually displaying the campaign stops of all the candidates in the 2008 presidential election. You can choose to limit the presentation of the map by candidate and date, of which many can be included. A great additional feature is the left-hand column that displays up-to-date media coverage relating to the presidential campaign. This site will no doubt be useful for both pundits and the general public. Check it out regularly.
