 Pennsylvania is a closed primary state, meaning that you have to be registered with the party to participate in primary elections. So do we know that this guy voted in a primary? Try to find that out. Remember that. Write it down so you don't forget. Did he vote in a primary? If so, who did he vote for? Would there be records of that? Yes, there were. There is no evidence currently. That he voted. Right. In any election at all. Then why would he be registered? Presumably... How do you register?
