Like the rest of eastern Oregon, the majority of registered voters who are part of a political party in Union County belong to the Republican Party. In the 2016 presidential election, 65 percent of Union County voters voted for Republican Donald Trump, while 25 percent voted for Democrat Hillary Clinton and 10 percent of voters either voted for a Third Party candidate or wrote in a candidate. These numbers show a large shift away from the Democratic party towards third-party candidates when compared to the 2012 presidential election, when 63.2% of Union Country voters voted for Mitt Romney, 32.9% voted for Barack Obama, and 3.8% of voters either voted for a third party candidate or wrote in a candidate. In 2020, however, the third party turnout dropped to 2.62% and Joe Biden won 28.47% of the vote, but the Republican lean remained with Trump winning over 68% of the vote.
