I haven't seen this story mentioned yet. Apologies if it has already been diaried - this place has been very busy lately.
Sarah Palin claims that she "took on the corrupt politicians of her own party".
Yet the Washington Post reports that from 2003-2005 she served as a director on a 527 called "Ted Stevens Excellence in Public Service Inc."
Stevens has, of course, since been indicted for seven felony charges.
However, Stevens' corruption has been reported on going back to the time that Palin was involved with him. For instance, see this LA Times article from 2003:
Among the ways that Stevens became wealthy:
* Armed with the power his committee posts give him over the Pentagon, Stevens helped save a $450-million military housing contract for an Anchorage businessman. The same businessman made Stevens a partner in a series of real estate investments that turned the senator’s $50,000 stake into at least $750,000 in six years.
* An Alaska Native company that Stevens helped create got millions of dollars in defense contracts through preferences he wrote into law. Now the company pays $6 million a year to lease an office building owned by the senator and his business partners. Stevens continues to push legislation that benefits the company.
* An Alaskan communications company benefited from the senator’s activities on the Commerce Committee. His wife, Catherine, earned tens of thousands of dollars from an inside deal involving the company’s stock.
It is also worth noting that not only does this tie her to Stevens, but it's also directly at odds with John McCain's supposed opposition to 527 groups.
