As per the usual, Sarah Palin added her uninformed two cents to the whole vile-rapper-Common-performing-at-the-White-House melodrama. She appeared on Fox News and made a statement saying that the White House lacked judgment in inviting Common to perform, because he's known for violent lyrics.
And don't get it twisted, she's not anti-hip-hop. In fact, she knows the lyrics to "Rappers Delight." The jokes just write themselves but skip to about 3:45 and hear the words right out of her mouth.
Props to Humanity Critic.
