I am skeptical such a scandal will have much of an effect on Obama's campaign. While it is not clear what exactly the story is, from the hint it sounds like something that happened during the last election as well which did not get much play.
Give the expected time frame, we will not have to wait long to find out.
"Sources told Secrets that the Obama campaign has been trying to block the story. But a key source said it plans to publish the story Friday or, more likely, Monday.
According to the sources, a taxpayer watchdog group conducted a nine-month investigation into presidential and congressional fundraising and has uncovered thousands of cases of credit card solicitations and donations to Obama and Capitol Hill, allegedly from unsecure accounts, and many from overseas. That might be a violation of federal election laws.
The Obama campaign has received hundreds of millions in small dollar donations, many via credit card donations through their website. On Thursday, the campaign announced a record September donor haul of $150 million."
