http://www.foxnews.com/politics/2011...g-voter-fraud/Despite many instances of electoral fraud internationally, in the U.S. a major study by the Justice Department between 2002 and 2007showed of the 300 million votes cast in that period, federal prosecutors convicted only 86 people for voter fraud – and of those few cases, most involved persons who were simply unaware of their ineligibility. This rarity of electoral fraud in the U.S. follows from its inherent illegality. Harsh penalties aimed at deterring voter fraud make it likely that individuals who might perpetrate the fraud correctly fear that they will be discovered by election officials carefully examining voter identification.
After a five-year hunt for voter fraud, the Bush administration's Justice Department came up with little widespread fraud, finding mostly cases of people mistakenly filling out voter registration forms or voting when they didn't know they were ineligible, The New York Times reported in 2007. But none of the cases involved a person voting as someone else.
