Both candidates will do OK.
hillary will know all the questions in advance and have scripted poll driven and focus group tested answers for each one that she has rehearsed
and rehearsed
and rehearsed
dont expect hillary to blow her lines
no one who is voting for hillary today will find any reason to change their vote tomorrow
trump will be less scripted and more likeable.
he has a chance to change some undecided or mushy middle voters minds.
BUT, there will be one question designed specifically to trip him up
that question is what the news media and the hillary campaign will focus on after the debate.
