Politics

From 1928 to 1996, Iron County voted Democratic in presidential elections, the only exception being Richard Nixon's landslide in 1972. In 2000, George W. Bush became only the second Republican since 1920 to carry Iron County despite narrowly losing the national popular vote, and the county remained a competitive county for the next three elections, narrowly voting for Kerry in 2004 and for Romney in 2012. Recent elections have seen the county trend solidly Republican however; in 2016, Trump won the county with 59.2% (the first time a Republican had won an outright majority in the county since 1920), and in 2020, he increased his vote share to 60.8%, and further expanding it to 62.6% (a difference of 1,070 votes) in 2024.
