Philadelphia is undergoing a massive transit strike. Normally, although a hassle for city residents, a local strike wouldn’t make national news. But Pennsylvania has another name —Pennsyltucky. It’s a mix of rural residents likely to vote red and city dwellers likely to vote blue, which means it’s a key battle state.  Transit officials have said if the strike is still on during election day next week, they’ll seek an injunction to send workers back to their jobs.
