I disagree strongly that this will hurt McCain. I don’t see how this reflects poorly on Sarah Palin at all. Its not like she lied or tried to cover it up. True she didn’t announce it to the heavens when she first accepted the nomination. However, she had her daughter where an engagement ring on her ring finger so its not like she tried to cover it up either. The only thing that this will do is make the KOS folks look like absolute scumbags who drudged up a skeliton in her daughters closet. If anything this will endear her more to conservative Christian families because she did the right thing and encouraged her daughter to get married and have the baby.
It really is a private family matter.
