Two charts assess Donald Trump’s distinctive debate style

WHEN DONALD TRUMP and Kamala Harris debate for the first time on September 10th, two very different speaking styles will be on display. Mr Trump talks and talks. His speech at the Republican National Convention, in July, was reportedly scripted to last 40 minutes. It was supposed to reinvent him as the unifier of a polarised country mere days after he had survived an assassination attempt. Instead he extemporised heavily, going on the attack so energetically that the few “unifier” bits were quickly forgotten. And he delivered the longest nomination-acceptance speech at a convention in modern history, at 92 minutes. Ms Harris, by contrast, spoke for just 38 minutes at the Democratic convention last month.
