Story highlights Overall, 52% who watched tonight's matchup thought Clinton did the best job

The poll finds one of the sharpest demographic divides among debate-watchers is education

(CNN) Hillary Clinton won the final presidential debate, topping Donald Trump by a 13-point margin according to a CNN/ORC poll of debate watchers, giving Clinton a clean sweep across all three of this year's presidential debates.

But Wednesday's debate watchers were closely divided on which candidate they trusted more on the issues most important to them.

Overall, 52% who watched tonight's matchup thought Clinton did the best job, to the 39% that thought Trump did. That's a tighter margin than in the first two debates. After the first debate, 62% of those who watched said Clinton won, 27% Trump, followed by a 57% Clinton to 34% Trump margin for the town hall debate held October 9.

Half of voters (50%) who watched Wednesday's debate said Clinton agreed with them more on the important issues, while 47% thought Trump did, but by wide margins, they thought Clinton had the better understanding of the issues, 61% to 31%, and was better prepared to handle the presidency, 59% to 35%.

Still, most said their minds weren't changed by tonight's debate, 54% of those who watched said it would have no effect on their vote, and those who did feel swayed were about evenly split between Trump (23%) and Clinton (22%).
