The Presidential Election Surge
The most predictable driver of high voter turnout in Nebraska is a presidential race. When a contest for the White House is on the ballot, Senate elections benefit from the heightened national attention and increased voter engagement. Data consistently shows that Nebraskans turn out in much greater numbers during these years. For example, in presidential election years like 2020, overall turnout of eligible voters was significantly higher than in the preceding midterm election of 2018. In 2020, incumbent Ben Sasse won re-election with over 583,000 votes in a year that saw robust participation. This pattern holds true for other presidential years, where Senate candidates ride the wave of national interest, leading to turnout rates that often
crest well above 60% of eligible voters.
The Midterm Mid-Point Lull
Conversely, midterm elections almost always see a significant drop in participation. Without the draw of a presidential contest, Senate races in Nebraska often struggle to generate the same level of enthusiasm. On average, turnout in midterm years can be about 20% lower than in presidential years. For instance, the 2014 midterm election saw a voter turnout of around 41%. However, some midterms do break the mold. The 2018 election, held during President Donald Trump's first term, saw a midterm turnout of 58% of registered voters in Nebraska, the largest in that timespan, demonstrating how a polarizing national environment can energize voters even without a presidential race on the ballot.
How Competition Fuels Turnout
A snoozer of a race is one of the surest ways to keep voters at home. When a Senate seat is seen as a safe bet for one party, turnout can stagnate. For years, Nebraska's Senate races have been reliably Republican, with the last Democratic win occurring back in 2006. However, the 2024 regular general election offered a compelling case study in how a competitive race can shift the landscape. The contest between incumbent Deb Fischer and independent candidate Dan Osborn was unusually close for the state, with Fischer winning 53.2% to Osborn's 46.5%. This tighter-than-expected margin signaled a level of engagement and uncertainty not often seen, likely contributing to a higher-than-average interest for a midterm cycle. In contrast, the concurrent special election that year saw a much wider margin, with Pete Ricketts defeating his opponent by more than 24 points.
The Changing Electorate and Modern Factors
Since 1990, the mechanics of voting and the makeup of the electorate have evolved. The rise of early and mail-in voting, a trend that accelerated significantly in 2020, has changed how and when Nebraskans cast their ballots. While intended to increase access, the impact on overall turnout numbers can be complex, sometimes shifting when people vote more than if they vote. Furthermore, Nebraska’s voter registration data shows a state dominated by registered Republicans, who make up nearly 50% of the electorate, compared to about 26% for Democrats and 22% for independents. This strong partisan lean often defines the starting point for any Senate race, but the growing bloc of independent voters, as demonstrated by Dan Osborn's strong showing in 2024, represents a potential wildcard in future elections, capable of shaping outcomes if they mobilize.
