In July 2010, Minnesota Majority, a conservative watchdog group, conducted a study in which they flagged 2,803 voters in the Senate race for examination, including 1,359 they suspected to be ineligible convicted felons in the largely Democratic Minneapolis-St. Paul area. Subsequent investigations of Minnesota Majority's claims by election officials found that many of their allegations were incorrect. Some of the cases that were submitted involved mistaking a legal voter for a felon with the same name, others involved felons who had had their voting rights reinstated after serving their sentences, and others were felons who illegally registered to vote but did not vote in 2008 election. Ramsey County officials narrowed their investigation to 180 cases, while Hennepin County examined 216 cases.
