What Trump has demonstrated is that in our present cultural environment, and in the Republican Party’s present state of bankruptcy, the first lines of defense against a demagogue no longer hold. Because he’s loud and rich and famous, because he’s run his campaign like a reality TV show, because he’s horribly compelling and, yes, sometimes even right, Trump has come this far without many endorsements or institutional support, without much in the way of a normal organization, clearing hurdle after hurdle where people expected him to fall.
But the party’s convention rules, in all their anachronistic, undemocratic and highly-negotiable intricacy, are also a line of defense, also a hurdle, also a place where a man unfit for office can be turned aside.
