Pink - Dear Mr. President

I heard Pink's Dear Mr. President on the radio a while back and I thought the song was good. I had no idea it was Pink singing it. I kind of mentally had her categorized as one of these modern pop singers that has no substance. However, eventually I found out who it was, and I really can't deny that this song is good. Most famous musicians wimp out of such politically charged songs, so I give her a lot of credit for singing it.
