Nor does any ‘unconsolidated’ presidential democracy, nor any presidential authoritarian system.

It is a vestige of the past, and the few other examples (Argentina, 1940s-50s Cuba) are all gone.

There are electoral colleges for the heads of state in some parliamentary systems, but these are a very different beast, both in the nature of the office being elected and in the nature of the electors themselves.

And then there is Bolivia: The only case other than the USA where the candidate with the most votes in a single round of popular voting could be denied the presidency (in Bolivia’s case because congress makes the selection if there is no majority in the popular vote).

That’s good democratic company, no doubt.
