I mean, my local couciller won on a platform of wanting to arrange after school care for kids at the local primary school. It doesn't take a lot at the local level. Nor can anyone at that level do all that much harm.

Best case, these people get genuinely into their roles and find out what issues face local governments (Hint: It isn't vaccines).
Worst case, they are completely nuts and vote against everything because it isn't about vaccines. But there are usually 8 councillers on the council and they can reign that sort of thing in.
