WASHINGTON POST: “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. Instead, the campaign is scrutinizing its books for improper donations after the money has been deposited.”
