"3 A.M. Girl Wants Obama to Answer Call" (with video)

ABC News, with video (02:27):

Casey Knowles of Bonney Lake, Wash., was recently watching Jon Stewart lampoon Hillary Clinton's well-known "3 a.m." ads on "The Daily Show" when her brother noticed something.

"They were parodying this ad, kind of poking fun at it. They were replaying it. We paused it. My brother was like, 'Is that Casey?' And we just erupted," Knowles said on "Good Morning America Weekend Edition" today. "Sure enough, it's me."

An image of an eight-year-old Knowles appears in the ad, shown sleeping soundly in bed. The Clinton campaign legally purchased the file footage of Knowles from Getty Images.

Clinton's ad aimed to emphasize her experience and say she'd be a strong national security candidate. The ad was a play on a 1980s-era advertisement with a similar theme: if there was a middle-of-the-night national security emergency, who would you want to have answer the phone and deal with it?

Ironically, though, the now-17-year-old Knowles would want Clinton rival Barack Obama to answer any important 3 a.m. calls coming into the White House.

Knowles' image originally was shot for a railroad company advertisement, but the teen said she harbors no resentment toward the Clinton campaign for using her image.

"I'm just enjoying the irony. I'm an Obama supporter," said the high school senior, who will turn 18 next month, well before the election in November.

Still, Knowles made it clear she disliked Clinton's ad.

"What I don't like about the ad is it's fear-mongering. I think it's a cheap hit to take. I really prefer Obama's message of looking forward to a bright future," Knowles said. "I think that's a much stronger message."

Since her identity was revealed, Knowles said the Obama campaign has reached out to her and she offered a suggestion.

"I mentioned that we should make a counter ad, me and Obama, against Hillary," she said. "They thought that was really funny. They actually might take me up on it."

Even if the campaign opts not to utilize Knowles' suggestion, she plans to continue stumping for her presidential pick. Already, she played an active role in his campaign.

"I've been campaigning for Obama for a long time. I actually called a lot of people around my area and got them to come out and caucus for him. I was a precinct captain at my caucus in February," Knowles said. "I'm actually a delegate for my precinct and I can go on to county, state and even potentially the national convention in Denver."
