The FBI is launching a voter fraud investigation into the community organizing group ACORN. The McCain campaign has accused ACORN of fraud in spearheading one of the most successful voter registration efforts in US history. Over the past year and a half, ACORN has helped sign up more than a million mostly young, mostly poor people to vote. Registration forms submitted by ACORN campaigners in a few areas around the country have been found to contain false or fraudulent names. ACORN officials have condemned the cases and insist they only amount to a tiny percentage of their registered voters. In an interview with the website Talking Points Memo, former New Mexico federal prosecutor David Iglesias criticized the probe, calling it “a scare tactic.” Iglesias was one of prosecutors dismissed in the Bush administration’s attorney firings scandal. He was let go in part because of his refusal to pursue voter fraud cases sought by Republicans.
