Okay, I am answering this question here as it will probably come up again somewhere along the way.
CGCS is not connected to the John Kerry campaign, or an official extension of that campaign. It is a collection of people who participated in the JK online forum and elsewhere and in that way is an extension of a community that was built there.
CGCS is paid for and run by an individual who was a volunteer at the online forum. The cost for this site is $20 per month unless the bandwidth increases and right now is paid for by one individual.
The moderators and administrators who volunteered their time at the JKOF wanted to continue the community and are continuing to volunteer their time.
