Unfortunately that's how politics works. Most people switch off when politics gets mentioned which is why the politicians that shout the loudest and repeat their mantra's over and over again to the point of believing what they say is actually true, usually get the vote.
You only have to look back to last year and see what BoJo and Fromage were shouting about over and over again and how their lies turned into believable 'truths' to see what I mean.
there used to be a local councillor (what happened to Mike Cuthbert-Murray?) that was like that. He used to say the same (UKIP) lies over and over and eventually he believed they were true himself!
