He already looks like a phantom, and on the campaign trail over the next four months, he forever seems on the verge of falling apart. When he speaks to crowds he shakes, rushing through speeches when he’s not stumbling; sometimes the words run into each other as if spoken by a drunk man or, worse, a man seized by a stroke. On planes and buses after each rally, he crumples into seats, passing out in a sweat, fevered by dark providences and the irredeemable. He’s bleached of color, seems to be disappearing before everyone’s eyes. He already was old before his time when she met him in London nearly two years ago and now he’s older still.
