The ballot question (question 3) is worded sneakily, such that voting "yes" means "keep the existing law [that protects trans people from discrimination]" and voting "no" means "repeal the law."
This is in contrast to most ballot questions I've seen, where a "yes" means "change something" and a "no" means "keep the existing law the same."
A yes on 3 is a vote for keeping the existing law that protects trans people!!
