The toughest aspect of writing a speech isn’t so much the rhetoric, it’s the ideas—which take time to incubate and develop, says Andrei Cherny, editor of the journal Democracy and a former White House speechwriter under Clinton. “The hardest part about writing a speech like this is not the mechanics of it but what you want to say and how you’re going to say it, the strategy of it,” Cherny says. For a speech of this magnitude it’s not uncommon for politicians and their staffs to work on language for months, going into double-digit drafts, according to Cherny.
