Despite its rural and post-industrial character, Berkshire County delivers Democratic presidential margins that rival dense urban cores, a pattern rooted in its arts-economy towns and a college presence anchored by Williams and Bard at Simon's Rock.
The Democratic margin in Berkshire County peaked at fifty-four points in 2012. By 1988 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. Berkshire County's median household income of $76,013 sits well below state and national norms, and 11% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Cuyahoga County and Philadelphia County.
