Obama Accepting Untraceable Donations

Juan Proaño, whose technology firm handled online contributions for John Edwards's presidential primary campaign, and for John F. Kerry's presidential campaign and the Democratic National Committee in 2004, said it is possible to require donors' names and addresses to match those on their credit card accounts. But, he said, some campaigns are reluctant to impose that extra layer of security.

"Honestly, you want to have the least amount of hurdles in processing contributions quickly," Proaño said.

Sen. John McCain's campaign has also had questionable donations slip through.

Dan Pfeiffer, Obama's communication's director, said that "no organization can fully insulate itself from these problems. The McCain campaign has accepted contributions from fraudulent contributors like 'A for You,' 'Adorable Manabat,' 'The Gun Shop,' and 'Jesus II' and hundreds of anonymous donors."

But R. Rebecca Donatelli, who handles online contributions for the McCain operation and the RNC, said security measures have been standard in the GOP nominee's fundraising efforts throughout the campaign. She said she was "flabbergasted" to learn that the Obama campaign accepts prepaid cards.

"Yes, a gift card would go through the same process as a regular credit card and be subject to our same back-end review," the Obama campaign said in its response to questions about the use of such cards.

Campaign finance lawyers said there is a long history of debate within the FEC about how to ensure that donors use their own credit cards.

Election lawyer Brett Kappel said the FEC has never grappled with the question of cash cards. "The whole system is set up for them to accept the payment, then determine whether it is legal or not. And if it's not, send it back. That's what the statute requires," he said.
