Andrew Jackson was the last Democratic Party candidate to win the county, in 1832. The county has been solidly Republican in Presidential elections since John C. Frémont's win against James Buchanan in 1856. The only exception was William Howard Taft's loss to Theodore Roosevelt of the Bull Moose (Progressive) Party – which had splintered from the Republican Party – in 1912.[37] The county has also voted for Republican Senators,[38] State Treasurers,[39] and State Auditors[40] for decades. Robert P. Casey is the only Democratic gubernatorial candidate to win the county in the last fifty years.[41] The county seat of Lewisburg is heavily Democratic, having given Joe Biden over 70% of its vote in 2020. However, the rest of the county is overwhelmingly Republican.[42]
