They found out he registered for voting as a woman, but I haven’t seen which Party, if any.
Not registered to either party - Unaffiliated’ or something like (abbreviated) that on the voting card.
He (she?) is registered as "UNA", unaffiliated.
Although, now, the registration information is missing from the ColoradoVoters website.
