Pennsylvania has maybe 150,000 Jewish voters; Ohio has half that many. Out of 5-6 million voters in each state, that’s grasping at straws!
For the sake of argument, let's say your numbers are correct. That would still mean that the Jewish voters could be decisive if the race in PA is decided by two points or less or if the race in Ohio is decided by one point or less. Neither of those scenarios are outside the realm of possibility.
