Yesterday, I brought you the results of three scientific polls showing the public thought Hillary Clinton was the winner of the first presidential debate -- the CNN Poll (Clinton 67% - Trump 27%), the YouGov Poll (Clinton 57% - Trump 30%), and the Public Policy Polling survey (Clinton 51% - Trump 40%).
Now a fourth poll has been released. It is the Politico / Morning Consult Poll -- done on September 26th and 27th of random national samples of 1,421 registered voters (and 1,253 likely voters), with a margin of error of 3 points.
This poll also had Hillary Clinton as the winner of the first debate (Clinton 49% - Trump 26%). The debate didn't change a lot of minds though (see bottom chart). Only 9% said the debate had changed their mind about who to vote for, while 81% said it had not changed their mind. But in an election this close, a swing of 9% could be huge.

A fifth poll has also been released now. It is the NBC News / SurveyMonkey Poll -- done on September 26th and 27th of a random national sample of 7,541 likely voters, with a margin of error of 1.6 points. The results of that poll are in the charts below. Hillary Clinton was also viewed as the winner of the debate in this poll (Clinton 52% - Trump 21%).
