So, I don't know why this isn't more prominent and why it isn't attached to every post about the Lieberman-Lamont race. (If this is a dupe, let me know and I'll delete it.)
If you're in Connecticut today, kudos. If not, you can sign-up to phonebank with MoveOn.org right now. It's really easy, and fun, and a good way for those of us not in the Northeast right now to help out.
That's it. Go sign-up. Go make calls. Go!
