Pennsylvania election law requires an automatic recount if the difference between the top two candidates for a statewide office is 0.5% of the vote or less.
Such a recount has been triggered five times since the law was enacted in 2004 — most recently in the Commonwealth Court race in November. Republican Senate candidates Mehmet Oz and David McCormick were well within 0.5% of the counted vote early Wednesday morning, with the vast majority of votes counted.
If that gap doesn’t widen enough as the final votes are counted, the race may head toward recount territory.
