People tolerate being lied to by politicians because they see it as politicians having to convince others to go along with a plan they believe and agree with. They don't see it as politicians lying to them, it's politicians who they approve of and agree with lying to others to convince them to go along with an agenda they approve of.
In other words, it's okay for politicians to lie because the supporters of those politicians believe they are in on the lie.
