From "This is True"

WAKE-UP CALL: In what will probably become the iconic TV ad of the 2008 presidential campaign, a little girl is shown sleeping as the "phone rings at 3:00 a.m. in the White House." The spot, for Hillary Clinton, is meant to convey that she is "ready on day one" to handle crises -- and imply opponent Barack Obama isn't. The little girl featured in the ad is now 17; the footage had been sold to a stock house, and was used by the Clinton campaign without bothering to learn who it was. It was Casey Knowles of Bonney Lake, Wash. She turns 18 well before the election, and she has already been working for a presidential campaign: Barack Obama's. (Tacoma News Tribune) ...When called to comment on this crisis, Hillary refused to answer the phone.
