Can Trump master 'the art of debate?'

In the only presidential debate of the cycle, with the election eight days away, the Republican presidential candidate spoiled his victory by failing to keep his cool amid intense and unexpected pressure from the moderators and his opponent.

The moment was fictional — written in the pages of Jim Lehrer’s 1995 novel, The Last Debate — but it echoes the very real concerns of voters who support Donald Trump and fear a similar catastrophe could unfold if he enters his first debate against Hillary Clinton without adequate preparation.
