The problem is partly that the entire-framing of what a working government requires is wrong..

A political-party with a leader..

that isn't working, never has worked for the best of any first-past-the-post country, & never will.

Just as the Indigenous peoples often had different kinds of Chiefs for different dimensions of their lives..

• Peace Chief for maintaining proactive/strategic harmony
• War Chief for dealing with existential threats from others
• Shaman for dealing with the deep end of reality
• Grandmothers for dealing with the questions that neither males nor young-people were competent at understanding .. etc ..

What the world actually requires is a system whereby the different kinds of leaders required to competently lead a country ALL get put in place.

Jugmeet Singh's a people-person, and he could be there both for, & with, people better than anybody else I know-of in Canadian federal politics..

but he isn't the guy who I'd put in charge of Strategy, or the person whom I'd put in charge of Implimentation, or the person I'd put in charge of Emergency Services & Military..

the right-framing would require a team, not an individual.

There's a book "Rocket Fuel" which is on how nearly-all businesses get 1 thing wrong:

most businesses mistakenly ignore that a visioneer usually isn't an implimenter.

Implimenter's closer to bean-counter.

Visioneer's closer to .. lunatic.

The book Change Intelligence identifies that people-people are 1 of 3 major kinds of leaders required...

the other 2 being thinkers/visioneers, & the implimenters..

You REQUIRE all-3, or you're not having enough traction to accomplish what you're supposed to be doing!

The business-culture's incompetence, however, is that it presumes that the COO of a company ( who is an implimenter ) ought be the next CEO ( which is kinda what happened to Beoing: they ended up with no engineer-visioneer, only bean-counters, & the whole religion of the company became poison.. NASA did the same thing when it compromised engineering for "business" culture, with the Challenger shuttle )

The problem is that you can't put a person whose nature fits only 1 of the required-roles, into a different required-role.

NONE of our countries bothers differentiating between the required-roles & then works to get the right person into each of those roles, none!

That is, at global scale, Darwin Award territory.

We KNOW the more complex the leadership, or management, problem, the better-quality the team required, we KNOW the structural-diversity of the team is key to having it be more-capable in different ways..

we won't do what's required??

( PS: never expect any political-system to tolerate required-evolution.

World-death would be preferable to political-motivation, compared with actual transformation to a different apolitical kind of system,.

Sad but true. )
