WASHINGTON (CNN) - The political advocacy group MoveOn.org is getting out of the 527 business.
"While MoveOn Political Action has always been funded exclusively by small donors like you, we've held open the MoveOn.org Voter Fund – a separate "527" organization – which can raise money from big donors. We haven't actually taken any big-money checks since 2004," MoveOn.org Executive Director Eli Pariser wrote in an email to the group's members. "In light of the new politics offered by Barack Obama, I've come to believe it's time to close the 527 forever."
The presumptive Democratic presidential nominee has said he does not want "527s" and outside, independent groups advertising on his behalf in the general election. A "527" is an political organization that can raise money in high dollar amounts and launch political advocacy campaigns, including television ads.
Past prominent "527s" include the "Swift Boat Veterans for Truth," a group that in 2004 attacked Sen. John Kerry's war record and arguably contributed to him losing his White House bid. But few had the impact of MoveOn's.
The group will retain its political action committee, which can take donations up to $5,000, though the group says the average donation hovers in the $50 range.
Even though its 527 is going away, MoveOn.org is not completely heeding Obama's request to stay off the airwaves. Last week, the group teamed up with one of the biggest labor unions, the American Federartion of State, County and Municipal Employees, to go up with a national television ad criticizing Sen. John McCain's position on the Iraq war.
The impact of outside groups this cycle is still up for debate. Since Obama's request some Democratic leaning groups have seen their donor base thin, forcing them to abandon paid media plans and instead shift gears to focus more on research and message. Obama referenced the past power of 527 groups as a factor in deciding to opt out of public financing for the general election.
