Why has Pennsylvania been such a battleground lately?
Growing up in the early 2000s and mid 2010s, there was little doubt Pennsylvania would go blue in a presidential election, and in 2012 there weren't that many TV ads on the presidential/senate races. Pennsylvania wasn't also considered a top 5 battleground, let alone the most major battleground back in the early 2000s and mid 2010s. But today, why has Pennsylvania been such a big battleground? Outside groups spent a combined 1 billion on ads in the presidential/senate races in 2024, compared to just $20 million on ads in 2012.
