I wouldn't get too worried. Many English Commonwealth countries (England, Canada, Australia, New Zealand etc etc) have open end governments meaning that a single political party is voted for usually for a 3-4 year stint. If they do a good job the people vote again and may keep them in. This can go on forever if the people continue to vote that party in.

Admittedly it is not perfect. For example, a party can be re-voted in based on the leader, but then the leader stands down and their deputy takes control. Not so good if your deputy was Dick Cheney lol.

But then again, I think we have learnt that voting in the US is not always fair, so it may leave the system open to abuse.

Well see that's the thing. Its not a party line vote we're talking about. Its the position of one of the, if not THE most powerful person in the world. Given public reaction to him, and his decidedly apparent Messiah complex, this should be an issue of grave concern.
