Personally, I don't give a shit. It happens all the time. But I bet it's still embarrassing to the right wingers, or whatever you want to call the republicans. McCain claims he knew. The article also states that the republicans are announcing it now to counter this weekend's rumors of Palin being the grandmother of her newborn. So, in other words, they're politicizing a 17 year old's pregnancy.
