Ah, good point, my mistake. So if I've got it right, the common usage would be "government official" for administrative positions, and "politician" for elected?
That's welll over 97% of the meaning[0] but for some reason I must say more. I'd be very surprised if anyone described am elected judge in America as a politician, even though they're elected.
If bribed with cash, maybe, unless it can fall under "campaign finance". Sports tickets, dinners, and gifts are generally accepted though.
