Every time someone repeats the lie that lying politicians are expected and accepted, they're helping make the lie true. Stop it.

This is why so many politicians are completely unable to concede a single point, even when it's completely obvious they're wrong, even when conceding the point wouldn't damage the strength of their argument. The rules political rhetoric are simple: disagree with all arguments and facts of those you oppose and never ever ever admit you're wrong. The moment you say you made a mistake your opponents will mercilessly use it against you and your supporters will perceive you as weak.
The whole political game is not fact based and never has been, in no country at no point in history. It's about teams. And people want their team to WIN, facts be damned.
I would argue that lying has nothing to do with expectations. Magicians and comedians lie, but we are okay with it and we (hopefully) don't believe those statements. We just get our chuckles and forget about them.
Many (not all) people expect politicians and other leaders to lie. And like you said, maybe we need them to lie, maybe the world is better for it. And I am sure there are plenty of politically correct terms to use for those instances instead of lying.
But if the statement is false, then it is false. It doesn't matter how the recipient of the message interprets it, that's their problem.
