Ancient greeks said that the greatest political orators and rhetoraticians are those who use their own voices raised in public speech. Dangerous demagogues, carismatic, self fealing charlatans who seek power to advance their own ends rather than that of the country, do the precise opposite in their public speeches. The best political orators must be emotionally rousing, yes, but not at the expense of reason and human co operation and tolerance. Be suspicious of candidates whose oratory rhetoric moves audiences to violence against other audience members.
