This is beyond my capabilities, but I'm sure there are plenty of people here (including Kos himself, of course) who could do this.
Imagine a "bat" graphic with a high goal ($1 million?) that keeps a running total of the number of pledges and total amount pledged.
If the DNC committee members saw how much money they would immediately raise from mostly small donors (i.e., the kind they could keep coming back to) it might go a long way toward dispelling any lingering concerns about Dean.
So, is anyone here up to the task of setting up such a site and getting the word out about it? (Of course, all of us here could and would help with the latter.) I think it would be important to have a SINGLE site everyone goes to rather than a morass of duplicative sites, as is now the case with the Dean petitions. And I think the promise of money would impress the DNC insiders a LOT more than petitions!
