Politics

Owing to its Yankee influence, Lawrence County has been reliably Republican for a full century. It was the only South Dakota county to remain loyal to Herbert Hoover in his landslide 1932 loss. In fact, Lawrence County was the second-westernmost county, behind only Utah's Kane County, to never vote for Franklin D. Roosevelt. The only Democratic presidential candidates to carry Lawrence County have been Woodrow Wilson in 1912 and 1916, and William Jennings Bryan in 1896. Lawrence County has also been one of the most consistent strongholds for the Libertarian Party, giving their 2016 nominee, Gary Johnson, one of the largest vote share out of any county outside his home state of New Mexico, with 7.9%. In 2020, Libertarian Party nominee Jo Jorgensen received 3.9% of the popular vote, her second best performance in any county during the election cycle.
