Turns out that William F. Buckley Jr. took the measure of Trump in an essay written way back in 2000 for Cigar Aficiando. (By the way, if only Marvin Shanken had taken my advice and started Trophy Wife Aficiando, this essay on Trump would have fit even better there.) National Review helpfully reprints most of it today, but here are the most relevant two paragraphs:
What about the aspirant who has a private vision to offer to the public and has the means, personal or contrived, to finance a campaign? In some cases, the vision isn’t merely a program to be adopted. It is a program that includes the visionary’s serving as President. Look for the narcissist. The most obvious target in today’s lineup is, of course, Donald Trump. When he looks at a glass, he is mesmerized by its reflection. If Donald Trump were shaped a little differently, he would compete for Miss America. But whatever the depths of self-enchantment, the demagogue has to say something. So what does Trump say? That he is a successful businessman and that that is what America needs in the Oval Office. There is some plausibility in this, though not much. The greatest deeds of American Presidents — midwifing the new republic; freeing the slaves; harnessing the energies and vision needed to win the Cold War — had little to do with a bottom line.
So what else can Trump offer us? Well to begin with, a self-financed campaign. Does it follow that all who finance their own campaigns are narcissists? At this writing Steve Forbes has spent $63 million in pursuit of the Republican nomination. Forbes is an evangelist, not an exhibitionist. In his long and sober private career, Steve Forbes never bought a casino, and if he had done so, he would not have called it Forbes’s Funhouse.
