Trump continued on his pro-life stance, and said that during his presidency, abortion would be a state issue, and he brought forth several negative points in Hillary's position, one of which is that under her plan, all abortions, including late-term and partial birth abortions, are legal. Hillary continued to be on the defensive on this one.
In my opinion, Trump won this round because of his ability to appeal to morality, and to defend his position effectively.
Hillary continued her vague stance on gun control, claiming that she would create "common sense" gun laws that would, according to her, keep children safe and reduce firearm accidents.
In my opinion, Trump won this round because he had a clear stance on this issue, and did an excellent job presenting it.
This debate was no contest. Trump was on the offense for the entire debate, and he was hammering Hillary on all the issues. He was consistent on his positions, and he showed confidence that wasn't in previous debates. Trump handily won this debate.
