Privacy of presidential primary? [View all]

The Sun-Sailor (the suburban freebie) has an editorial concerns about the privacy of the upcoming presidential primary. In regular primaries, we get one page (of candidates, that is, the other is judges and ballots) one side is R the other - D.

But next March we will have to request either an R or a D. And the editors are concerned that if someone wants to know, for example, what ballot the owner of the McDonald next door, then this info can be plastered on Social Media. Or if an employer wants to get rid of someone... Or the preferences of non partisan office holders (we know, this, really). The editors want to assure the privacy of this process.

But I thought that, since we all had to write our names, and addresses when attended caucuses, that this info is available, if someone wants to go through all the pages?

No?
