Sen. Barack Obama's presidential campaign is allowing donors to use largely untraceable prepaid credit cards that could potentially be used to evade limits on how much an individual is legally allowed to give or to mask a contributor's identity, campaign officials confirmed.
Faced with a huge influx of donations over the Internet, the campaign has also chosen not to use basic security measures to prevent potentially illegal or anonymous contributions from flowing into its accounts, aides acknowledged.
In recent weeks, questionable contributions have created headaches for Obama's accounting team as it has tried to explain why campaign finance filings have included itemized donations from individuals using fake names, such as Es Esh or Doodad Pro. Those revelations prompted conservative bloggers to further test Obama's finance vetting by giving money using the kind of prepaid cards that can be bought at a drugstore and cannot be traced to a donor.
The problem with such cards, campaign finance lawyers said, is that they make it impossible to tell whether foreign nationals, donors who have exceeded the limits, government contractors or others who are barred from giving to a federal campaign are making contributions.
The Obama campaign has shattered presidential fundraising records, in part by capitalizing on the ease of online giving. Of the $150 million the senator from Illinois raised in September, nearly $100 million came in over the Internet.
The Obama team's disclosures came in response to questions from The Washington Post about the case of Mary T. Biskup, a retired insurance manager from Manchester, Mo., who turned up on Obama's FEC reports as having donated $174,800 to the campaign. Contributors are limited to giving $2,300 for the general election.
