WASHINGTON AND NEW YORK — One of the few times Barack Obama lost his famous cool during the presidential campaign was the day photographers got too close as he walked his youngest daughter, who was dressed as a corpse bride, to a Halloween party near their Chicago home. "You've got a shot. Leave us alone," Obama barked.
The moment revealed Obama's ambivalence even as he prepared to move his daughters -- Malia, 10, and Sasha, 7 -- into the fishbowl known as the American presidency: when to share them with the country and when to snap the curtains shut.
As the youngest children to occupy the White House since the Kennedys', the Obama daughters -- or Rosebud and Radiance, as the Secret Service dubs them -- are poised to serve a dual role in America's new first family. They humanize a future president seen by some as aloof, while presenting an image of vitality to a nation mired in economic despair.
Already, there is talk of sleepovers, bedroom makeovers, soccer balls and a hypoallergenic puppy at a White House that for years has seemed cloistered and off-limits. Glimpses of the girls fidgeting and yawning as their parents voted on election day, or kissing the president-elect goodbye as he dropped them off at school offered a point of personal connection with everyday Americans, whether or not they voted for Obama.
But sharing his daughters with the country exposes them to the harsh scrutiny that has plagued first families since the nation's founding, ever more pervasive in today's relentless news cycle and often-vicious blogosphere.
Past presidents took varied approaches. The Clintons virtually hid Chelsea, who was 12 when she came to the White House, from mass media exposure. Over the objections of his wife, President Kennedy beckoned photographers into his children's lives; Jackie was out of town when the celebrated under-the-desk photograph of John Jr. was taken.
The Obamas have signaled they will land somewhere in between, allowing discreet peeks at a family life that includes Uno tournaments and charades, bike rides and a lot of reading aloud. (Malia and her father cracked the Harry Potter series together.) But most of it will be presented with images, narration and little direct access. "Right now they're not self-conscious . . . they don't have an attitude," Obama said of his daughters in a "60 Minutes" interview that aired Sunday, calling their well-being "one of my greatest worries."
"If at the end of four years, just from a personal standpoint, we can say they are who they are -- they remain the great joys that they are -- and this hasn't created a whole bunch of problems for them, then I think we're going to feel pretty good."
Obama has struggled throughout his political life to reconcile his ambition and his children, often lamenting missed soccer games and family dinners. When he couldn't attend one of Sasha's dance recitals -- 20 6-year-olds in red cowboy hats tapping to "These Boots Are Made for Walkin' " -- he was "broken up about it," Michelle Obama recently told the Associated Press.
Friends portray the Obamas as protective parents, the family closely knit despite his grueling schedule. As Illinois' junior senator, he spent workdays at the Capitol and evenings in a spare one-bedroom apartment writing his books. On weekends he returned to the family's $1.6-million home on Chicago's South Side and cocooned with his children. On the campaign trail, aides say, he called them every night, sometimes by webcam, flew home to pick up the Christmas tree and never missed a parent-teacher conference.
"Books are a huge bonding between him and his daughters," said Ann Walker Marchant, a friend of the Obamas and a former special assistant to President Clinton. Marchant predicted children's literature will find a shelf in the Oval Office. She recalled vacationing with the Obamas on Martha's Vineyard when Sasha asked her father, hoarse from the campaign trail, to read to her. "He could hardly speak but as long as she wanted him to read, he read."
Because young families rarely occupy the White House, the Obamas beg comparison to the Kennedys. Caroline and John Jr. -- 3 years and 10 weeks old when they moved in, respectively -- reinforced the fresh, youthful image that defined their father's presidency.
But in many ways, the two families could not be more different, one shaped by an elite pedigree and the other by hard work and an absent father. It's difficult to imagine Michelle Obama -- who mixes designer dresses with off-the-rack J. Crew -- ordering her children's coats from a London fashion house as Jackie Kennedy did, or letting a pony named Macaroni graze on the South Lawn.
