Carbon County historically has been the base of Democratic Party support in strongly Republican Utah with its sizable blue-collar population. It voted for Bill Clinton in 1992 and 1996 by wide margins. In 1964 Lyndon Johnson carried 72.7% of votes in the county. At the state level it was no less Democratic; in the 1992 gubernatorial election it was one of two counties (the other being Summit County) that voted for Democratic candidate Stewart Hanson over Republican Michael Leavitt.
After the turn of the millennium, however, Carbon County has trended Republican. It voted for George W. Bush in 2000 and 2004, while voting for the Democratic gubernatorial candidates. In 2008, John McCain won Carbon County with 52.60% of the vote, versus 44.59% for Barack Obama. In 2012, the county's Democratic vote fell further as Mitt Romney carried 67.3% to 30.1% for Obama. In 2016, despite Utah's strong swing against the Republicans due to the presence of conservative independent Evan McMullin, Carbon County was the only county in the state to swing more Republican, as Donald Trump won 66% to Hillary Clinton's 21.5% percent.
