Political bellwether[edit]

Mercer County was previously considered a political bellwether for the state of Pennsylvania since its demographics, urban/rural ratio, and party affiliation once closely mirrored the state as a whole. In 2000, Al Gore carried it against George W. Bush. This trend failed to hold true during 2004 Presidential election and 2008 Presidential election, in which Mercer County voted more conservatively than the rest of the state. In 2004, George W. Bush won Mercer County with 51% of the vote. That year John Kerry won the state as a whole with 51% of the popular vote. In 2008, John McCain won Mercer County by fewer than 200 votes, as he and Barack Obama each received roughly 49% of the popular vote. Barack Obama won the state of Pennsylvania as a whole with 55% of the popular vote. Each of the three statewide office winners also carried Mercer in 2008. In 2016, Donald Trump won Mercer County by 12,403 votes. Trump also won the state of Pennsylvania. Each of the three Republican candidates for statewide office carried Mercer County in 2016. In 2020, Trump again carried the county, despite Pennsylvania narrowly voting for Joe Biden. Trump carried 62% of the vote, the largest majority for any major party candidate since 1964, and the largest majority for a Republican since 1928.[citation needed]
