A group of conservatives is suing Minnesota Secretary of State Mark Ritchie and 25 county election officials over what it characterizes as incomplete voter records.
Minnesota Majority president Jeff Davis says the counties failed to post voter history updates as required within six weeks of the November 2008 election.
His lawsuit also alleges that Ritchie's office has yet to update voter records to reflect all those who voted.
Ritchie's spokesman didn't immediately return phone messages.
Davis says 400,000 more ballots showed up in the State Canvassing Board's report than the number of voters in the statewide voter registration database.
The lawsuit asks the Minnesota Supreme Court to declare the officials in violation of state law and make them pay attorneys' fees for the plaintiffs.
