Ah, beautiful beautiful irony!
Casey Knowles is a high school senior in Washington state. Like a lot of people her age, she's a big Obama fan. She's even gotten involved as a precinct captain for the Democratic caucuses, and could be a convention delegate.
Unlike a lot of people her age, about a decade ago she did some film work, and appeared as a sleeping kid in some footage shot for a railroad company ad. Getty Images got the rights to that stock footage. The Hillary Clinton campaign bought it from Getty Images, and used it in the now famous "3 a.m. phone call" ad.
Yes, the girl in the Clinton ad supports Obama.
