Brief Political History

In the six presidential elections until 2016, Montgomery County has voted for the Democratic candidate, but not by large margins. However, in 2016, Republican Donald Trump narrowly defeated Democrat Hillary Clinton. Montgomery County was also the most populated county in Ohio to go for Trump in 2016, and it was the only county in Ohio to flip for Joe Biden in 2020.
