Colorado: proven election fraud

The Heritage Foundation's database lists 23 proven election-fraud cases in Colorado since 1982, 23 of them since 2000, most commonly absentee fraud. Against 4,583,280 registered voters, the since-2000 cases equal 0.00050% of the rolls, or 1 in 199k registered voters. Per ballot, that is 1.27 cases per million presidential votes since 2000: 0.8× the national rate (below average), #30 of 51. Even here, proven fraud touches a vanishing sliver of the vote.
