Agree....he never got sarcastic or angry or belligerent.
Trump needs to calmly and with the right hitting words to the moderator, point out now biased he is and that it shows to everyone.. remind him to ask the same questions with the same follow ups to hillary. The victim does not have to take the onslaught the biased media hands out to Trump.
I remember when Newt told the moderator off in the last debate he was in (2012), and the audience gave a standing ovation to Newt.
