The County Committee rules require that every Election District has at least two seats, one female, and one male. So if you have a different-gendered person you know (maybe a roommate or a spouse or a friend) they are the ideal person to collect signatures with you. Plus it’s more fun and less stressful with a running-mate! (Some districts even have four seats: two women, and two men.)
For non-binary/gender non-conforming individuals, run for the seat with which you feel more closely aligned.
