Greg Sargent, TalkingPointsMemo: MoveOn, the advocacy group supporting Barack Obama, has decided to permanently shutter its 527 operation because of his insistence that such groups should not spend on his behalf during the general election, I've learned from the group's spokesperson. By shuttering its 527, MoveOn is effectively killing its ability to raise money in huge chunks from labor unions, foundations, and big donors who would give over $5,000.
