It's interesting that in the UK the traditional two-party system is broken, because everyone realises that both of the traditional parties have been bought by rich folk and business interests, only serve their own interests, and can't be trusted any more. The main contenders now are Reform and The Greens, a situation that no-one predicted five years ago.

The same is true in Australia, though there's no charismatic left-wing leader emerging, and the Farage-equivalent is a laughing stock who struggles to be coherent at times. But because of billionaire money, she's still up there on the polls.

The US system makes it much harder for new parties to form, so it's probably going to be factions in the existing parties. And, of course, MAGA is the new faction in the Republican party; effectively a new party itself. So the ground is fertile for a new left-wing faction in the Democrat party to rise.
