Before the debate, sixty-one percent of uncommitted voters said that they trust Obama on that; after, sixty-nine percent said that. For McCain, twenty-seven percent trusted him to manage health care before the debate; thirty percent said so afterwards.

Sixty-three percent think Obama will raise their taxes, while forty-eight percent think McCain will.
