"Any presidential candidate gets used to sleeping odd hours," says Edward M. Kennedy's press secretary Tom Southwick.

Normally Kennedy is an 8-hour sleeper, Southwick says. "But during a campaign he may get just five hours. He likes to take a day off every 10 days or so to catch up on sleep and relax with his family."

George Bush's campaign staff tries to make sure their candidate gets eight hours' sleep every night, says press secretary Pete Teeley. "When he's on the road, moving constantly, it's important to make sure he gets enough sleep so he's fresh."

On the campaign trail Ronald Reagan gets just 4 or 5 hours sleep, says an aide, noting that Reagon has the added discomfort of jet lag when flying East from his Los Angeles home."

Jerry Brown "is not a person who requires a whole bunch of sleep to function real well," says a press aide. "He sleeps about 5 hours a night."

When campaigning in Iowa, John Connally "went 40 hours without sleep for a media blitz," claims an aide. Usually "he get 5 or 6 hours."

Jimmy Carter reportedly goes to bed after the 11 p.m. news and is up and at work by 6 a.m. In crisis periods he may get even less sleep.
