Wisconsin has the most decentralized election administration in the country: elections are conducted by roughly 1,850 municipal clerks, canvassed by 72 county clerks, and certified by the Wisconsin Elections Commission (WEC), which also maintains the statewide voter registration system. For those who are interested in taking a deeper dive into the state's available data, we have prepared a quick guide to the available data and where to find them.
Wisconsin has the most decentralized election administration in the country. In this document, we identify the locations of available election data and their dedicated webpages at the state level. Because results below the state canvass, cast vote records, and voting-mode breakdowns exist only at the county and municipal level, we also cover the state's three largest counties.
