I'm pretty thrilled about the fact that I'm going to be spending the week leading up to Election Day in Ohio as a volunteer for Victoria Wulsin. Nicholas, if I remember correctly, is going down to Tennessee to help Harold Ford. If things go right, helping out in this election will be the sort of thing that you'll be allowed to get a little St. Crispin's Day about in the future.
But if you want to "stand a tip-toe when the day is named" years hence, you don't have to travel far. Consider the Call for Change program at MoveOn. They've identified Democrats in key areas who usually don't get around to voting in midterm elections, but who might do so if somebody just called and asked them. If your cellular plan has free evening or weekend minutes, take advantage!
