KANSAS CITY, Mo. - Officials in Missouri, a hard-fought jewel in the presidential race, are sifting through possibly hundreds of questionable or duplicate voter-registration forms submitted by an advocacy group that has been accused of election fraud in other states.

Charlene Davis, co-director of the election board in Jackson County, where Kansas City is, said the fraudulent registration forms came from the Association of Community Organizations for Reform Now, or ACORN. She said they were bogging down work Wednesday, the final day Missourians could register to vote.
