County commissioners

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 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.
