The results from late Wednesday night showed 52 percent of debate watchers calling Clinton the winner compared with 39 percent who thought Trump won the night. 
Clinton's 13-point margin is the closest in CNN's polls of the three debates. She won with a 23-point margin during the second debate, earlier this month, and she won the first debate in September by a 35-point margin.
Clinton also bested Trump on the question of who seemed better prepared to be president: She won with 59 percent of the sample compared with 35 percent for Trump. 
But the two were effectively tied on who seemed more sincere and authentic, as well as whom the respondents agreed with more on important issues. 
The debate in Las Vegas was the final face-to-face bout for the presidential hopefuls with less than three weeks left before Election Day. 
The candidates steered clear of personal attacks for the most part, a departure from the earlier debates. But Trump made the most talked about comment of the night when he refused to promise to accept the results of the election.
