A bad back doomed any chance Perry stood to break through. It became an open secret that he was using painkillers in sufficient dosages to keep him standing through the two-hour debates. The manager of a rival campaign was at a urinal in an empty bathroom in Hanover, New Hampshire, before the Bloomberg News debate on October 11, when he heard someone come through the door loudly singing “I’ve Been Working on the Railroad.” Wondering who was making all the noise, the campaign manager turned his head and saw, to his surprise, the governor of Texas. Perry came down the row of about twenty urinals and stood companionably close by. Nonplussed, the campaign manager made a hasty exit; as the bathroom door closed, he could hear Perry still merrily singing away: “I-I-I’ve been working on the ra-a-i-i-l-road, all-l-l the live-long day …” Asked about the episode, a top campaign official said, “He whistles. I wouldn’t read anything into it.”
Oof, Rick Perry. (Politico via Gawker)
This explains so much.
