I don’t know anything about Kentucky demographics.
alot of the NYers who moved to Florida (some are my relatives), came from the post WWII generation that settled in suburban places like long island. they are republicans in other words, not all the NYers in Florida are from NYC.
A lot of Californians are Republicans, too. Are you contending that only {or primarily} Liberal Californians are prone to move and only to NV, CO and NM?
