At the presidential level, Grundy County is reliably Republican. Like many of the rural counties throughout Missouri, Donald Trump carried the county easily in 2016 and 2020. Bill Clinton was the last Democratic presidential nominee to carry Grundy County in 1996 with a plurality of the vote, and a Democrat hasn't won majority support from the county's voters in a presidential election since Lyndon Johnson in 1964.
Like most rural areas throughout northern Missouri, voters in Grundy County generally adhere to socially and culturally conservative principles which tend to influence their Republican leanings. In 2004, Missourians voted on a constitutional amendment to define marriage as the union between a man and a woman—it overwhelmingly won in Grundy County with 77% 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 Grundy County with 55% 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 Grundy 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 Grundy County with 61% of the vote. The proposition strongly passed every single county in Missouri with 79% 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. 63.53% of Grundy County voters cast their ballots to overturn the law.
