… In the fluid stages of the campaign, debates can produce a media narrative that gives a long-shot candidate a temporary bump or, maybe more important, contribute to the rise or fall of a front-runner.

That makes the debate the perfect chance for a couple of candidates — but probably not more than that — to at least temporarily change their trajectory. CONT.
