Opposition research is as old as politics itself—Cicero's orations against Catiline, a dodgy candidate for the Roman consulship in 63BC, were notably well-informed.
You also had statesmen like Pericles, whose famous funeral oration brags about the golden democracy of Athens with rhetoric that wouldn’t sound out of place today.
Sixthly, I would require a speaker to stop when he is done, and not hang a string of those useless habensingewesengehabdhabengewordensigns to the end of his oration.
