John McWhorter in Persuasion:
Donald Trump is incapable of meaningful participation in such an event. Only in the sense that “match” can apply to both chess and mud wrestling could the word “debate” apply both to the Kennedy-Nixon event and to Trump’s on-stage behavior. Trump cannot help but distort a debate into a cage-fight. He will, again, shamelessly lie and endlessly interrupt.
This is especially problematic because Trump’s behavior during such events can be misleadingly seductive. Being highly focused on the details of political issues is by no means a human universal, and probably should not be. But this means that what can determine elections, especially with our modern media, is charisma. To many, Trump’s unplugged alpha splatter lends an enticing sense of vigor, strength, and even leadership quality.
