'coming back' means they lost their job at some point. And Trump hasn't 'come back', because he's still in his first ever term as a politician (and it's extraordinarily difficult to fire him - a US president has literally never been successfully impeached, though one retired to avoid it possibly happening). I also never said that this was an ironclad rule and that you were permanently dismissed from your position, never to return again in your lifetime. But if you do lose your position, it's far from guaranteed that you'll get it back; it's a considerable risk to lose it, hence folks in authority play it safe.

Are you saying though, that France has not seen politicians and other positions of authority say less of substance than in past decades? That they're not watching their tongues any more than they used to? That errant comments aren't taken out of context by the public and used to vilify the person who said it? Well, more power to you; the rest of us should be so lucky - all over the anglo world, this pattern has been noted, rising with the 24-hour news cycle (which rewards 'gotcha!' journalism).

You don't even need to go as far as France. RI and NJ do that too.
