A federal agency created to restore confidence in the election process in the wake of Bush v. Gore sits all but leaderless as the country approaches Election Day. As local election officials scramble to sort out last-minute issues — Palm Beach County, Fla., for example, recently hired dozens of workers to hand copy about 27,000 misprinted absentee ballots — the U.S. Election Assistance Commission operates, on its 10th anniversary, as a shell of what Congress designed it to be. Its four commissioner spots are vacant. The executive director resigned last year. Its general counsel left in May. It has lacked a quorum to conduct official business for almost two years. Congressional gamesmanship has hamstrung the commission by neither giving it necessary resources nor eliminating it outright. “It’s a national embarrassment that this agency, whose only mission is to provide information, doesn’t have a single commissioner,” said Rick Hasen, an election law expert at the University of California, Irvine.
