Whether it is negative personal attacks and general negative campaigning, the public are turned off by blind, unthinking, tribal political loyalty and the resultant school yard behaviour.
Because they are not blindly politically loyal. They are too busy trying to get from day to day and from week to week. And they are primarily worried about how they are able to do that.
Politics and politicians only really register on their radar if they are perceived as being able to help (seldom) or as actually getting in their way (mainly). “What’s in it for me?” is a valid thought process from the public.
Politicians can be a welcome breath of fresh air by simply focusing on what’s good for their constituents and saving the squabbles and the petty.
