yeah i think madison co. is probably the best bellwether county for ky gov, as it will be close and important to either candidate's path to victory--so important that
cameron even launched his general election campaign there (although tbh i can imagine a scenario for either one to lose madison co. and still win). i think nelson and boyle co. will also be good indicators; if beshear wins both then he wins statewide. if beshear wins daviess it's absolutely over for cameron (although given its in the central time zone, by the time it would be called for beshear it would probably already be clear that he won). if cameron flips back the northern kentucky counties beshear won in 2019 then the race is probably over too.
