Physicians across Pennsylvania are politicking in unprecedented ways with less than a month to go before the midterm election, making the case that the abortion restrictions proposed by Republicans would threaten one of the state’s most important economic sectors.

They’re flanking Democrats at campaign rallies and knocking on doors in flippable state legislative districts. They are registering patients and colleagues to vote. At town halls and in ads, they warn that doctors, residents and medical students will avoid a state where they could be prosecuted for helping a patient terminate a pregnancy — damaging one of the largest and most recession-proof pieces of the economy.
