Last Night's Democratic Debate: Tough to Evaluate

    Both Obama and Clinton did well last night. There are two ways to read this. Some might say that by holding his own with the more "experienced" candidate, Obama emerges as the real winner. Others would say that with Clinton apparently holding a small lead, all she had to do was make sure he didn't outshine her.
    You be the judge. On Tuesday, we'll know what difference last night made, if any.
