My understanding of the PA primary is that the candidates themselves aren't featured on the ballot at all; voters elect the delegates directly. Though my question then is how do the voters know who these random names listed on the ballot are pledged to?
There is a Presidential Preference question on the ballot; this decides 17 of the delegates.
The other 54 delegates are elected directly on the ballot, 3 per CD. Their preferences are not listed, so yeah the voters have no clue. The campaigns may make a push to educate voters, but I don't even know if the candidates have preferred slates in the first place. Yeah, essentially Pennsylvania will be electing 54 superdelegates.
