John Wayne/John Wayne Gacy, Elvis birth & death, Lexington & Concord, "Hoot Smalley" (actually Smoot-Hawley) tariff act & FDR when it was Hoover... and still others.
Actually not all of those examples were gaffs. But the gaff thing is not really the issue with you, is it?
Fact is, politicians make gaffs all the time. Amazingly like real people. Those who are gaff-free are so scripted one never does get a sense for who they really are. Moreover, in the give a take of every day politics are you really trying to tell me that none of those you adore with precious executive experience have ever gaffed. If you truly believe that I have a nice bridge in Brooklyn I can sell you cheap.
In debate your argument is called specious. It is a device used to redirect debate to the trivial or away from areas one does not wish to discuss.
I’m still curious as to who the wonderfully experienced and gaff-free person is that you support.
