It’s popularism. We had the same with Brexit. Many people who had the vote relate to candidates and arguments that highlight the problems and struggles everyday folk can see in the street and/or in popular press/social media.
There’s no solution or joined-up thinking policies associated with these opinion agreements. Just personalities that “relate to the common citizen”.
when these people actually get elected then that’s where the problems escalate. Electing “cool” and “in touch” with the people politicians leads to all kind of problems. They are inexperienced, have no understanding of how things work, can’t see a holistic view and end up screwing over the people who voted for them in favour of their own idealism (in best case), or personal wealth and power.
The sooner major parties reach out to the disillusioned the better. There are so many people on the fringe that feel they’re not represented is now so high that it is not a fringe minority anymore. These people are going to vote for the likes of Trump, Farage because they reinforce their concerns.
