"because you are better at argument does not make you right".

Yeah, but it almost always wins. Take for example the Quayle/Benson debate. The great line "You are no Jack Kennedy" was a huge zinger..

...but largely a non-sequitor. Quayle wasn't claiming anything but the same political experience as a young Jack Kennedy, but Benson, seeing a huge rhetorical vulnerability, handed perhaps the biggest single debate loss in political history with one line.
