Looking what's happening in the world of politics at the moment I'm not sure I'd agree with you there.
I think you mean what's happening with the electorate. Politics is not significantly different than it's ever been.
What we have though is an electorate that has bought into the narrative that feelings trump facts, that all opinions are equally valid, that the main-stream-media is all corrupt and that all politicians are the same. None of those things is true.
Trump was elected because far too many people in America simply don't give a flying fuck and couldn't be arsed to do basic due dilligence on a racist, misogynistic salesman.
'But people are fed up with politicians...' Yes, of course they are. In the same way that they are fed up with anything that requires thought, requires effort and isn't instantaneously gratifying. When the electorate gets it's news from Facebook & Twitter and that news is structured by algorithms that present you with the things you want to hear. So they vote for an idiot whose entire plan is characterised by three-word-phrases: 'Build-a-wall...' 'Drain-the-swamp...', 'Lock-her-up...'
'Politics' is governing a country or being the opposition that holds the government to account. That's a really, really fucking difficult thing to do. If someone tells you it's easy and can be done with a bunch of soundbites you need to kick them where it hurts and send them packing. If you're stupid enough to believe them... well we've seen what happens.
