Is it common for politicians to share speeches they wrote but never gave?
Hillary Clinton has made public the speech she would have given had outcomes been different in the 2016 US Presidential Election.
I can only think of one other example of a high profile politician sharing a speech they would have given (but didn't). That is a speech Roosevelt had written and intended to give in the event of the Normandy landings failing. (I read this in a history book some time ago, and from a quick google couldn't locate a reference to it, so I must apologise if it was not the President but the General, Dwight D. Eisenhower)
In any case, is it common for high profile politicians to provide copy of speeches they never actually gave?
