Your party affiliation is a matter of public record, and you're not required to vote for your party. Not really a big deal IMO. Any attempt by the election workers to suppress your vote based on your answer would be trivially detected by a number of security checks.
You're dodging the allegation. It's not that it's not public information or that it must dictate the vote. It's that there's no reason for the poll worker to ask or know what you party registration is prior to sending to you machine A or machine B. At best it's a non-issue, at worst it's an opportunity to steer voters to a broken machine.
Any comparison of total turnout v.s. historic turnout based upon political party could be done after the fact anyway.
I want to clarify that I don’t think drew is being dishonest here. I’ve never heard this requirement nor been asked my party affiliation in a general election. Primaries - yes.
Pennsylvania voter here - in 2018 they asked me for my party affiliation and then remarked (jokingly) on the fact that my affiliation was an extreme minority for the district. I was a bit put off by this. 2020 and a few districts over however, totally secret somehow. No idea what changed.
