Why do people say that Hillary won all three debates?

[Pandaguineapig]

The consensus among most voters (rather than punditry) is that Trump won the second debate while Clinton won the 1st and 3rd debates, in the end there was no "defining moment" or clip from the debates that could move public opinion by a noticeable amount

Exit polls also show people thought Hillary won the debates by 50-47 so really margin of error not the shelling many in the media made it out to be. Trump easily won the second debate and even though Clinton likely won the third debate, his "nasty woman" comment was one most Americans agreed with if you are to believe Hillary's favorability numbers
