Seems ACORN isn't the only organization that's had trouble with contractors submitting fraudulent voter registrations.
Via Firedoglake :
Faked names on voter registration forms. Error rates as high as 60 percent. Firing the people responsible for these errors. Investigations launched by local and state police. Sound familiar? This is not ACORN in the 2008 election's final days.
This is the California Republican Party and its contractors in 2006, when the same problems that are now dogging ACORN and providing political fodder for GOP attacks plagued an effort by California Republicans to register 750,000 people.
The details were all spelled out in a series  of Los Angeles Times stories, which quoted former California Democratic Party Chairman Art Torres saying these kinds of errors are inevitable  "when you use private vendors." Even the state's top election official in 2006, Republican Bruce McPherson, was forced to investigate  his own party's actions.
