Every county in Pennsylvania except Montgomery County voted for Democrat Robert Casey in his reelection bid for Governor. Casey won staunchly Republican Synder, Wayne and Union Counties, and is the only Democrat in the 20th or 21st centuries to do so.
That actually does surprise me. I would have thought Wayne would have voted Democrat for at least someone else in the past 100 years
Wayne County last voted Democratic at the Presidential level in 1892, for Grover Cleveland. Snyder and Union Counties have not voted Democratic since before the Civil War; in fact, the last Democrat that Union County voted for was
Andrew Jackson in
1832! That has to be the longest non-Democratic streak of any county in the country, at least of those counties that have voted Democratic at some point since 1828.
Wayne, Snyder, and Union were three of the four counties Barry Goldwater won in Pennsylvania in 1964. The fourth was Lebanon County; Franklin D. Roosevelt in 1936 was the last Democrat to win that county, and the only one since the Civil War, at the presidential level, to do so.
Another interesting fact is that in 1986, Democratic Senator Wendell H. Ford obtained 74% of the vote in Kentucky and won every single county in the state, even rock-ribbed Republican bastions like Leslie, Owsley, Rockcastle, Jackson, and McCreary, which have not voted Democratic since the Civil War. Ford is, to my knowledge, the only Democrat ever to sweep all of Kentucky's counties, at least in a presidential or Senate race (and almost certainly gubernatorial as well).
