She may have graduated with her class, but Bristol Palin has other things on her mind. When she got on stage at the Wasilla Sports Complex on Thursday night, the abstinence advocate mouthed to the audience, "Where's my baby?" She searched around until she found Tripp in the back of the room, in her aunt Heather's arms. After news of Bristol's pregnancy broke earlier this year, her mom, Gov. Sarah Palin, admitted in an interview, "Oh, there goes her education... And that's why I'm so proud of her... really relieved." But apparently Palin had nothing to worry about: Bristol graduated with a 3.497 G.P.A., and regretted only that she was "point zero-zero-something" away from graduating with honors.
