How we determined the most liberal cities in Pennsylvania for 2026

To find the most liberal places in Pennsylvania, we used Saturday Night Science – the argument you’d make at a bar – to find the cities with the most liberals.

Straight forward.

We started by making a list of every city in Pennsylvania over 5,000 people based on the 2020-2024 American Community Survey. That left us with 193 cities and towns.

We then measured the voting record and MIT election data to determine which places lean the most leftward in their allegiances by:

  1. Percentage Of Votes For Democratic President In 2020

Because no voting data exists at the city level, we used county-level election results from the 2020 election. We assigned every city in a county the percentage of votes that went to the Democrats, effectively extending the county’s results to the city level. In cases where larger cities encompassed an entire county, the election outcomes accurately reflected the city’s political landscape.

The winner, Philadelphia, is “The Most liberal City in Pennsylvania For 2026”. The most conservative place in Pennsylvania was Punxsutawney.

We updated this article for 2026. This report is our eleventh time ranking the most liberal places to live in Pennsylvania.
