Sober or grim? You make the call. Handled some early light jabs from questioners and rivals with ease, although he fumbled a bit when apparently denying his own quote about lacking economic expertise. Eagerly welcomed another opportunity to rhetorically run against Hillary Clinton on Iraq. To his great benefit, his elegant, vital, and sharp-tongued mother was more prominently referenced than either Clinton, and he charmingly parried a question about her televised comment that he had limited support from the Republican Party. Graciously offered unsolicited praise of Giuliani's 9/11 record. Overall, though, was too often tense and forced in his delivery, rather than presenting himself as the happy warrior with a frontrunner's breeze at his back.
