So, I understand that in the hope of re-election, politicians often have to maintain a pretense of infallibility. The assumption being that they must have done everything right in the past, in order to do everything right in the future.
Reality does not reflect this pretense, human beings make mistakes, do selfish things and, for whatever reason, make bad decisions.
I can't bring any instances to mind where a politician has gone on record to state words to the effect of "I was wrong", "This was a mistake I made" or "That was a wrong turn". Are there instances of this?
