New Mexico The Republican Party of New Mexico alleges 28 people voted fraudulently in one Albuquerque state House district in the June Democratic primary.
Party representatives said at a news conference Thursday they found the suspect voters in a review of 92 newly registered voters in House District 13.
"We really have a bombshell - evidence of voter fraud in the 2008 primary in Albuquerque," said State Rep. Justine Fox-Young, an Albuquerque Republican.
Fox-Young said several of the suspect voters were registered by the Association of Community Organizations for Reform Now, known as ACORN, an advocacy group for low-income people that has come under fire in recent weeks for its voter registration practices.
On Thursday, the FBI announced a national investigation into whether ACORN has helped foster voter registration fraud. The organization also is being investigated for fraud in Nevada, Connecticut, Missouri and at least five other states. Election officials also have recently questioned the group's voter forms in Ohio and North Carolina.
