Today is the third and final debate. Hillary is leading in the polls, Trump's ship is sinking, he’s the underdog and desperately needs to win this debate, not only to stop her momentum, but also to appeal to women, blacks, Hispanics, men with college degree and young voters, since with 40% voter base he cannot win the election.
All Hillary needs to do is remain calm and presidential, as she was in the previous two debates, explain her policies with depth and clarity, and don't feed the troll, let him bark, he is good in self-destruction.
