A poster on the thread discussing the FEC request by Kerry said that he/she had received more than one e-mail from Moveon.org and that in their e-mails they give a link to the Kerry campaign for donations.
Now that, to me, sounds like coordination.
Moveon.org giving a link to contribute to the Kerry campaign does indeed sound like it's at least worth investigating.
Problem is that the FEC doesn't want to get involved in regulating 527s until 2005 at the soonest.
