@snood,
I haven't seen the debate, but no doubt Hillary is smooth. She can talk and her rhethoric is superb and to the point, not to mention how quickly she responds to adverse questionings as we've seen at the Benghazi hearings.
Hillary has a huge team of experts coaching her along and they're clever and
shine the light on her perfectly from every angle. Obama came off as a loser in all debates he had with Hillary in 2008 and his rhethoric is by far superior to Sanders.
Having an excellent publicits and an entire team who feeds you with the perfect answers, is quite powerful. What Hillary cannot convey is sincerity and honesty. How can she be when the biggest crooks - banks, endorse her?
