G.O.P. Is Taking Aim at Advocacy Groups

By CARL HULSE and SHERYL GAY STOLBERG

WASHINGTON, March 30 — To many Republicans, the liberal activist organization MoveOn.org is a political boogeyman that they hope to chase off with new restrictions on so-called 527 groups.

But the pursuit may turn out to be fruitless. Like other major groups planning to inject themselves aggressively into the midterm elections through advertisements, voter drives and issue fights, MoveOn.org has already figured out what it thinks is a better, and less controversial, way to spend its millions. Its 527 — named for a section of the tax code — is being put on ice.

"Our 527 is dormant," said Eli Pariser, executive director of MoveOn.org. He said his group would predominantly operate as a conventional political action committee, allowing it to more freely mix explicit political support and issue advocacy in a way that Mr. Pariser described as "squeaky clean."
