I like the idea of voters engaging would be voters. The concept would work for any group. I think for Democrats it is likely to be more effective due to their "underdog" status. As of this writing, the site is brand new. There are just over 100 names on the list. I'll take a peek at them closer to the election to see how its working.
Here's what they ask:
> Promise to show-up and vote against Bush/Cheney
> Promise to make reminder-to-vote calls right before the election
> Ask everyone you're planning to call to join the phone tree too
The website leaves no doubt about its pupose. It is scratch built to engage its visitors in the effort to de-elect President Bush.
