It is possible to have many discussions concerning the US Government and its electoral system.
It is also possible to have many discussions concerning the UK Government and its electoral system.
Taking the UK first, for good or ill, the UK has a non-elected “Head of State”.
This “Head of State” has almost no “powers”, except to dismiss any Government and “require” that the “people” elect a new “Government”.
As far as I know, this has never been tested in the UK.
However, this same “Head of State” is “represented” by “Governors General” in her/his “Dominions”.
It came to pass that one of these Governors General had a problem in that the Prime Minister of the Parliament of the “Dominion” concerned had not the numbers in the “Upper House” to pass the “Supply Bills”, which were necessary for paying “Civil Servants” and the “Defense Forces” of the Dominion.
That Governor General, in the name of the “Head of State”, chose to dismiss the then current Prime Minister, and appoint the Leader of the Opposition to that post, on the condition that “Supply” would be granted, no other legislation would be passed – which the Governor General would not have agreed to in the name of Her Majesty – and that an election would be called in the shortest possible time.
The system worked.
There was no revolution.
The people voted and elected a new Government.
Contrast this with the situation in the USA.
The US “Founding Fathers” chose to replace a non-elected Monarch (with diminishing powers at the time) with an elected President, with quite considerable powers.
While they chose to have limitations on such powers to be scrutinized by “Congress” and with it the possibility to have the President “impeached” and dismissed, the US President still has powers greater than any other “democratically elected” president – depending on how one might construe “democratically elected”.
Many things would unnecessary if the USA simply had a “Non Executive” “Head of State” President, as does Ireland, Germany, India and many other countries, not to mention the “Constitutional Monarchs” of the UK and many European Countries, Japan and even Thailand.
The problems that ensued when the "Head of Government" in Germany took upon himself the office of "Head of State" in that country are manifest.
