Preview of Sunday Night's CNN Democratic Debate

    This week's Tote Board column contains a preview of this Sunday's Democratic debate. Briefly, here's what to look for:

    Obama: Needs a better, more seasoned performance than last time. His thoughtful stump style doesn't translate easily into a debate format so it will be interesting to see how he adapts.
    Clinton: Can she be warmer and more likeable? It sounds trivial but she has to find a way to reduce her negatives.
    Edwards: Now that Clinton and Obama have matched his stand on Iraq, how does he remain the candidate of the liberal activists?
    Richardson: Perhaps his last chance to get things going: After a mediocre debate last time and a performance last Sunday on Meet the Press that some have described as the least impressive in the show's history, he has to do better.
    Biden: Worth watching as the only Democrat on the stage who supported last month's Iraq war funding package. May be involved in some of the debate's more memorable exchanges.
    Dodd: Can he get noticed?
    Kucinich: Going nowhere though he doesn't seem bothered by it.
    Gravel: Could say anything and probably will.
