And politicians have realised this.
As proven in recent years.
This actually isn't a go at Tory voters, I think if the roles were reversed other voters might act exactly the same and also not care about any of the above as long as their side won. I remember reading about an election in the US a while ago were one of the two candidates had just been arrested for child sex abuse, he didn't lose any support despite this. Some of the electorate were interviewed and said better him that the other guy. I can't remember which party was which but I don't think it matters, I don't think it would have made much difference if it was the other way around.
We should demand better, it's our fault politicians lie, cheat, are racist and break the law, we let them.
