Wisconsin: proven election fraud

The Heritage Foundation's database lists 68 proven election-fraud cases in Wisconsin since 1982, 68 of them since 2000, most commonly felon voting. Against 3,933,068 registered voters, the since-2000 cases equal 0.0017% of the rolls, or 1 in 58k registered voters. Per ballot, that is 3.19 cases per million presidential votes since 2000: 2.0× the national rate, #7 of 51. Even here, proven fraud touches a vanishing sliver of the vote.
