I think the appeal is reaching the pinnacle of political office, that has to be worth all the nonsense around it for those who aspire, and reach that level.
To be a politician at any level, you have to have an inbuilt belief that you are good enough to make a change, and that belief must increase exponentially with any, and all, realised ambition you have as well.
The problem is, as we know, politicians are like monkeys, the higher they climb, the more of their unpleasant parts we can see.
The difficulty now appears to lie in the Tory Party's unseemly haste to jettison their PM before he could do any more damage, without actually looking ahead carefully enough to see who was next.
That's why they followed America with Trump, and didn't get the person they wanted, just the other person, who wasn't the one they didn't want.
Of course, that's no basis for choosing a crossing warden, never mind a Prime Minister, and that's why we are where we are now.
And to tie that in with the Question - Ms Truss possesses all the desire and ambition needed to make the horrible job something to aspire to.
Sadly, she also lacks any of the basic requirements to do it even satisfactorily, never mind actually doing it well.
Ambition and belief motivate those who aspire to climb this greasy pole, but they need experience, political skill, management skill understanding, brains, wit, oversight, man-management, and an ability to convince the electorate that they are fit to be voted in for another term.
Of course, Ms Truss has the desire and the ambition, but sadly none of the other attributes, not one.
Desire and ambition make you want the job, they don't guarantee that you can do it once you get it.
