Instant Brief Analysis Following CNN Debate -- Giuliani and Huckabee Stand Out

    A good night for Giuliani and Huckabee, but not for Romney, who seemed tired and hesitant virtually every time he was challenged. One debate does not a campaign make but if tonight is indicative, the race is going to come down to Rudy and Mike.  Maybe it was just this one observer's impresson -- and it was just one event -- but the rest of the field beyond those two seemed to be candidates for a cabinet office, not the presidency.
