Toplines

  • In 2020, President Trump received the highest number of votes ever for a Republican candidate and had the highest number of votes in 67 out of Wisconsin’s 72 counties.
    • Before Senator Ron Johnson’s historic performance in 2022, President Trump held the record as the strongest-performing Republican by net margin in 43 out of 72 counties.
  • President Trump’s vote totals increased by 14.6% from 2016 to 2020.
    • Kenosha County experienced the highest growth in Trump’s vote totals, with an increase of 24.8%.
  • Of the 13 fastest-growing counties, relative to their 2012 vote totals, President Trump won 12 out of these 13 counties and increased his performance from 2016 in 11 out of 13 counties. These counties are generally smaller and more rural.

Turnout

From 2012 to 2020, rural areas in Wisconsin have seen the highest increase in vote contribution share, growing by 1.8%, while urban areas have experienced the largest decrease, dropping by 2.7%.

The below charts highlight voter turnout trends in presidential elections from 2008 to 2020 and partisan differences in 2016 and 2020. Turnout among active voters peaked in 2012 at 88.8%. Partisan turnout shows modeled Republican voters maintaining high participation (88.9% in 2016 and 89.4% in 2020), modeled Democrat voter turnout decreased slightly, and Swing/Unaffiliated voters significantly increased their turnout from 76.1% in 2016 to 85.8% in 2020. This indicates that Swing/Unaffiliated voters remain a critical group to contact early and identify their support for further messaging.

AB/EV

Data Trust collects the AB/EV file from the Wisconsin Election Commission once every three days, allowing for immediate insights and targeting of individual voters.

The percentage of total votes cast through absentee ballots and early voting (ABEV) saw a dramatic increase in 2020, peaking at 72% in April 2020 (Supreme Court) and 60% in November 2020, before returning to pre-pandemic levels in 2021. This surge during the 2020 election during the COVID-19 pandemic, followed by a decline as conditions normalized, indicate that there was no significant change in ABEV voting in Wisconsin since 2020. There are already 151,000 voters who have indicated that they would like to always receive a ballot to vote by mail, and many more individual requests will come in as voters turn their attention to November.

There was a significant increase in the percentage of absentee votes cast by mail from 2016 to 2020, peaking at 83% in April 2020 (Supreme Court) and 67% in November 2020. These highs continued in the next two subsequent Supreme Court elections and appear to have stabilized around 60% in the most recent elections. This trend suggests a notable shift towards mail-in absentee voting during the COVID-19 pandemic, with some decrease post-pandemic, yet remaining higher than pre-pandemic levels.
