Here's something fun to do on the way home after helping out with GOTV efforts:
should you be popping by your local Barnes and Nobles (or Borders, or wherever) to pick up the great new Lakoff book, why not grab a few extra copies of My Life, Against All Enemies, or the 9/11 Commission Report and slyly plop them on top of the giant stacks of books being pushed by the big conservative publishers? maybe on top of Ann Coulter's new book--or Unfit for Command--or whoever you feel could use it.
This works well at your "big box" retailers such as Costco, too.
