How local do we have to get? Can the opinions of swing voters in like one county in PA hold the rest of the world hostage?
Polls indicate the majority of Pennsylvanians oppose fracking: https://penncapital-star.com/energy-environment/poll-majority-of-pa-residents-want-fracking-to-end/
"According to the Bureau of Labor Statistics, Pennsylvania had about 4,900 oil and gas extraction jobs in December of 2019. (For a frame of reference, there are more than 148,000 employed registered nurses in Pennsylvania. In January, there were 6.2 million jobs in Pennsylvania.)" https://www.pghcitypaper.com/news/pittsburgh-area-republican-candidate-sean-parnell-inflated-fracking-job-figures-by-a-lot-17001969
It's a very dedicated interest group with a lot of money behind it, but fossil fuels simply don't employ that many people, even in PA. It seems like an inadequate excuse for taking positions friendly to the fossil fuel corporations that are destroying our biosphere, both on the local scale and the global scale. Don't blame Pennsylvania for Harris reversing her position on fracking.
Also, while PA is undoubtedly a vital battleground, I want to mention that ElectoralVote currently has the tipping point state for both presidential campaigns as North Carolina: https://electoral-vote.com/evp2024/Pres/Tipping_point/Aug28.html
In other words, if Harris carries PA there's a decent chance she will also take NC by a slightly larger margin, and will already have secured the presidency without PA's electoral votes.
