I did see this: https://thehill.com/elections/4408071-almost-half-of-haley-supporters-say-they-would-vote-for-biden-over-trump-iowa-poll/amp/ saying that a sizable portion of Haley’s voter base would go for Biden over Trump in a general so I imagine part of the strategy is driving the point home for as many of the “moderate” republicans as possible.
Many examples in older mythology as well. Norse mythology makes reference to genderfluid characters and Greek and Roman mythology are filled with stories of characters’ genders changing for a variety of reasons.
