Macomb County has shown Republican tendencies in statewide elections, while tending to favor Democratic candidates at the federal and local level.  The county gained fame in the 1980s and '90s as a bellwether of state and national politics. Macomb's large cohort of working-class, socially conservative whites gave it one of the nation's most prominent concentrations of "Reagan Democrats". Outsider candidates with a conservative-populist bent have done well there in the past, such as Pat Buchanan in 1992 and Donald Trump in 2016.   Macomb County voters were primarily responsible for the failure of the Regional Transit Authority proposal to create a public transit system in the Metropolitan Detroit region.
