QuoteIn February, Republican legislators in Wisconsin ordered an audit of the 2020 election by a 6-4 vote. The Legislative Audit Bureau lists an Elections Administration audit as active, with expected completion this Fall. State Auditor Joe Chrisman, who supervises the audit, describes its scope in a February letter to the Joint Legislative Audit Committee.

Trump campaign had financed partial recounts in November 2020 of the largest and most liberal counties of Milwaukee and Dane, which resulted in an increase of 132 votes to Biden's margin of victory. Biden won Wisconsin by about 20,000 votes—the same amount Trump won by in 2016. The results of the Wisconsin election, including down-ballot, were certified by Governor Tony Evers soon after they were received, giving Biden 10 Electoral College votes.

The audit has latitude to review the performance and methodology of each Wisconsin electoral jurisdiction's voting system and its error rate, including absentee voting and the 62.1% that used electronic voting. The nation saw an increase in mail-in ballots, about double that trended Democrat with fewer rejected in 2020 than in years past. Mail-in ballots in Wisconsin, however, increased from 170k to 964k from 2016 to 2020 and made up almost 75% of the total—compared to a historical rate of only 6%. The Wisconsin state elections website FAQ maintains, "There is no evidence of widespread voter fraud in this or any other Wisconsin election." The FAQ goes to great lengths to address election integrity issues from all sides.
