I think MoveOn.org is getting too big for its britches.

From The Washington Post:

“I think Democrats understand that when we can join forces and work together, it’s very powerful,” said Eli Pariser, executive director of MoveOn Political Action. “And then when we can’t, it’s not fun.”

This month, MoveOn sent an e-mail message to members asking whether it should start organizing potential primary challenges against Democrats who were not tough enough on the war, a move that upset Democratic leaders. The group plans to announce the results of its survey on Monday.

Democratic leaders in Congress and presidential campaigns said they winced when they saw the MoveOn advertisement [attacking the credibility of Gen. David H. Petraeus]. While they may have agreed with its overall point, that the troop buildup has not worked, several Democratic officials said privately that the advertisement had been counterproductive.

They said MoveOn had handed Republicans a fresh talking point to criticize Democrats and turn the focus from Iraq in a critical week in the war debate.

Senator John Kerry, Democrat of Massachusetts, said on MSNBC that the advertisement was “simply over the top, and I think it’s inappropriate, period.”

Ms. Pelosi said on “Good Morning America” on ABC that she “would have preferred that they not do such an ad.”
