This is just delightful:

Casey Knowles is the sleeping 8-year-old girl appearing in a recent TV ad for Hillary Clinton about the proverbial 3 a.m. phone call. It's old footage; Knowles is about to turn 18.

And if you think her appearance constitutes an endorsement of Clinton, think again: Knowles supports Barack Obama, and has been campaigning for him.

Even better is that the footage the Clinton campaign used in their spot was originally shot for a railroad company ad. But now it's stock footage...and fair game for anyone willing to pony-up the dough and stick it into an entirely new narrative.

It is to laugh.
