The Giffords campaign has taken a leaf out of the Dean playbook with a local version of the Dean Bat. In this case a saguaro cactus replaced the baseball bat. It turned out to be remarkably successful. In addition to raising money it resulted in something like a ten-fold increase in hits on the web site, probably the result of folks checking in to check on progress.
