Election Fraud: A radical group Barack Obama used to work for is committing voter-registration fraud in several states, ahead of the election. What does Obama know about this scam?

It's a legitimate question to raise now that the FBI has raided the offices of the nonprofit Association of Community Organizations for Reform Now in Nevada and North Carolina, two states where Obama and John McCain are running neck-and-neck. ACORN has registered bogus voters in both states.

The group's voter-registration fraud is rampant, and authorities plan a nationwide sweep of ACORN offices to collect records.

In Nevada, state officials say the fraudulent registrations included forms for the starting lineup of the Dallas Cowboys football team, including quarterback Tony Romo.

"Romo is not registered to vote in the state of Nevada," Secretary of State Ross Miller said, "and anybody trying to pose as Terrell Owens won't be able to cast a ballot on Nov. 4."

While those names will be flagged on Election Day, felonious voters may have better luck using other cutouts. Nevada, along with several other key battleground states, requires no ID to vote.

In North Carolina, where Obama has been running nonstop ads, ACORN has registered a record number of new voters, many of them suspicious. Statewide, Democrats are doing better than the GOP in new converts — even in traditionally Republican counties.

There have been 218,749 newly registered Democrats in North Carolina since January — more than five times the 38,337 new Republicans, state records show.

The numbers show a startlingly close political battle even in Republican-dominated Union County, with 4,233 new voters registering as Democrats and 4,362 as Republicans. In previous election years, new Republicans have outnumbered Democrats 2-to-1 in the fast-growing Charlotte-area county.

In Missouri, one ACORN registrant named Monica Rays showed up on no less than eight forms, all bearing the same signature.

Suspicious election officials sent letters to some 5,000 ACORN registrants in St. Louis, asking the letter recipients to contact them.

Fewer than 40 reponded.

In Kansas City, 15,000 registrations have been questioned, and last year four ACORN employees were indicted for fraud.

In addition, ACORN officials have also been indicted in Wisconsin and Colorado. Investigations against others are active in Ohio, Florida, Pennsylvania and Tennessee.

ACORN has also been registering convicted felons — including inmates — in Florida and other battleground states. ACORN boasts registering a record 1.5 million new voters so far this election.

What does all this have to do with Obama, besides the fact that he'd be the beneficiary of most, if not all, of these new votes?

For starters, Obama paid ACORN, which has endorsed him for president, $800,000 to register new voters, payments his campaign failed to accurately report. (They were disguised in his FEC disclosure as payments to a front group called Citizen Services Inc. for "advance work.")

What's more, Obama worked as executive director of ACORN's voter-registration arm, Project Vote, in 1992. Joined by two other community organizers on Chicago's South Side, Obama conducted the voter-registration drive that helped elect Carol Moseley-Braun to the Senate that year.

The next year, 1993, Obama joined the civil-rights law firm Davis Miner Barnhill & Galland, where he sued the state of Illinois on behalf of ACORN to implement the federal "Motor Voter" law, which the GOP governor at the time refused to do. Then-Gov. Jim Edgar argued, presciently, that the Clinton law would invite voter fraud.

Obama downplays his ties to ACORN, and his campaign denies coordinating with ACORN to register voters.

Meantime, New Orleans-based ACORN maintains that it has no control over volunteers who are falsifying application forms, that they're like employees who steal from the store.

But the fraud is widespread and not isolated. It also turns out that some ACORN execs allegedly are involved in a $1 million embezzlement cover-up at their headquarters. Representing them in the case is none other than Michelle Obama's old law firm in Chicago.

ACORN's corruption is not just out in the field, as they claim. There's a pattern of corruption from the top down.

McCain would be wise to start preparing a challenge to voter registration rolls should he lose the race in a close contest. He'd be crazy not to contest the results in light of these events.
