At the presidential level, DeKalb County is solidly Republican. Donald Trump carried the county easily in 2016 and 2020. Bill Clinton was the last Democratic presidential nominee to carry DeKalb County in 1996. The last Democrat to win majority support from the county's voters was Michael Dukakis in 1988.
Like most rural areas throughout northwest Missouri, voters in DeKalb County generally adhere to socially and culturally conservative principles which tend to influence their Republican leanings, at least on the state and national levels. In 2004, Missourians voted on a constitutional amendment to define marriage as the union between a man and a woman—it overwhelmingly passed in DeKalb County with 80.7% of the vote. The initiative passed the state with 71% support from voters. In 2006, Missourians voted on a constitutional amendment to fund and legalize embryonic stem cell research in the state—it failed in DeKalb County with 55.9% voting against the measure. The initiative narrowly passed the state with 51% of support from voters as Missouri became one of the first states in the nation to approve embryonic stem cell research. Despite DeKalb County's longstanding tradition of supporting socially conservative platforms, voters in the county have a penchant for advancing populist causes like increasing the minimum wage. In 2006, Missourians voted on a proposition (Proposition B) to increase the minimum wage in the state to $6.50 an hour—it passed in DeKalb County with 67.7% of the vote. The proposition strongly passed every single county in Missouri with 78.99% voting in favor. (During the same election, voters in five other states also strongly approved increases in the minimum wage.) In 2018, Missourians voted on a proposition (Proposition A) concerning right to work, the outcome of which ultimately reversed the right to work legislation passed in the state the previous year. 65.70% of DeKalb County voters cast their ballots to overturn the law.
