Politics
Like Lewis & Clark County to the west, Cascade County leans Republican but has voted for Democrats four times since Lyndon Johnson's landslide in 1964. Hubert Humphrey easily won this county in 1968, one of nine counties that he was able to win. Barack Obama carried Cascade in 2008 but lost to Mitt Romney in 2012 by 9%. Since 2012, the county has voted Republican by comfortable margins. In 2020, Donald Trump won the county with over 58% of the vote, the best performance by a Republican since 1920.
In statewide races, Cascade County often acts as a bellwether county and has been friendlier to Democrats - Senators Max Baucus and Jon Tester have carried the county in all of their elections and Governors Brian Schweitzer and Steve Bullock carried it in all four elections in 2004–2016. Since at least 1984, no Democrat has won in Montana without winning Cascade County, however, Republicans have occasionally won statewide without carrying the county, such as former Senator Conrad Burns in 1988 and 2000, Governors Marc Racicot in 1992 and Judy Martz in 2000, Secretaries of State Bob Brown in 2000 and Brad Johnson in 2004, and Attorney General Tim Fox in 2012.
