Obama Let His 3-year-old Daughter Listen to Rap

In response to the vile rap song hip-hop star Ludacris recently made in support of  Barack Obama, the senator's campaign issued the following statement:

"As Barack Obama has said many, many times in the past, rap lyrics today too often perpetuate misogyny, materialism, and degrading images that he doesn't want his daughters or any children exposed to."

Yet, in this 2004 video, he talks about how his little daughter was enamored of a certain rap song, and it's obvious that he thought nothing of exposing her to such influences.

If Barack Obama would expose his 3-year-old daughter to this corruptive trash, what does this tell us about his judgment?
