When is a gaffe not a gaffe in politics? When it’s untrue, apparently. Enjoy the campaigns.
A classic gaffe, a career-threatening humiliation delightful to the press, is when someone expresses a home truth in plain language. Like that if a foreign nation attacked a country with which you had a defensive alliance you would defend them. You can have real trouble living something like that down.
It’s an especially juicy gaffe when someone blurts out what everyone knows.
