We are told again and again: his is the most improbable political story in decades, perhaps in history. And yet that a reality television megastar, as Trump might put it, could outpoll sixteen dimly to barely known politicians, some new faces, many also-rans, seems less than shocking. Did tens of millions ever cast their eyes on the junior senators from Florida or Tennessee or Texas, or the governor of Ohio, not the mention the ex-governors of Arkansas of Florida, or the ex-CEO of Hewlett Packard, before they chanced to mount the stage for a debate with Donald J. Trump last August, a television event that drew the unheard-of viewership of 24 million? Those 24 million tuned in to see trump. Only one man on stage gad a name as famous and by then it was in such disrepute that he had seen fit to replace it with an exclamation point on his campaign posters.
