Pennsylvania

Pennsylvania, where the U.S. Constitution was written, was the second state admitted to the Union, officially becoming a state in December 1787. The Keystone State has participated in all 59 presidential elections through 2020. Pennsylvania is generally considered a battleground state, although it voted Democratic in the six elections prior to 2016. That election saw Donald Trump win the state by 0.7%, one of three 'blue wall' states (Michigan & Wisconsin the others) he won on his way to winning the presidential election. Again competitive in 2020, Joe Biden won by 1.2%.

While still an important prize, with 19 electoral votes, Pennsylvania, like many industrial northern states, has seen population migrate away in recent decades. The state now has just half the 38 electoral votes it had a century ago.

Vertical lines before 1992, 2002, 2012, and 2022 show Census-related redistricting breakpoints. Geographic borders associated with district numbers may have changed.

The state had an additional redistricting before 2018. Same caution about borders applies.
