It's most likely not about the local leadership, but about the mindset of the voters.

Who has a better life expectancy? Person A who has health insurance and takes the necessary and recommended vaccinations, or Person B who takes Ivermecin as a cure-all without ever asking a doctors opinion until they are on the death bed and submits his baby to a measles party to gain a "healthy immunity"?

Guess which parties are Person A and Person B voting for.
