Progressives contend voter fraud is a myth, but are they behind a massive — and growing — case of it in Indiana?

The Indy Star reports Indiana State Police raided a non-profit group in connection with an investigation into fraudulent voter registration forms that have been found in at least nine counties.

According to the Star:

The investigation began in late August when police learned of the filing of fraudulent voter registration forms in Marion and Hendricks counties.

The investigation has expanded from Marion and Hendricks counties to include Allen, Delaware, Hamilton, Hancock, Johnson, Lake and Madison counties, according to a statement from State Police.

Police said the growing number of involved counties leads investigators to believe that the number of fraudulent records might be in the hundreds.

The possible fraudulent information is a combination of fake names, addresses and dates of birth with real information.

As part of the expanded investigation, State Police detectives served a search warrant for the business offices of the Indiana Voter Registration Project in the 2400 block of North Meridian Street.

“The group was altering already registered voter’s information. The group changed the voters address to an address not associated with the voter without the voter’s knowledge,” Secretary of State Connie Lawson said in a statement.

“An investigation of this nature is complex, time consuming and is expected to continue for several more weeks or months,” said a State Police statement, according to the paper.

“Victims of the activities by some agents of the Indiana Voter Registration Project may not discover they have been disenfranchised from voting until they go to vote and realize their voting information has been altered. Such action may result in the citizen having to cast a provisional ballot.”

The IVRP is apparently connected to a Washington, DC group called “Patriot Majority,” as they group denounced the raid.

“After all is said and done, when this partisan investigation finds no wrongdoing by the organization, Connie Lawson and the Indiana State Polic will have prevented 45,000 African Americans from voting in this year’s elections,” Craig Vargoa told Fox 59.

Varoga, in turn, ran to the Obama Department of Justice to complain about the investigation.

While one might assume that group would have limited government leanings because of its name, Patriot Majority counts as one of its successes helping to re-elect Nevada Sen. Harry Reid in 2010.

A hallmark of the group’s rhetoric is attacks on the libertarian Koch brothers.

“Last year, as well, we commissioned a national poll quantifying that a majority of Americans believe that billionaires like the Koch Brothers put profits before patriotism,” Patriot Majority claims.

But now, that same group is ensnared in a state investigation.
