Nate Silver: 'Every scientific poll I've seen' shows that Hillary won the debate
We now have four scientific polls on who won the debate:— Josh Jordan (@NumbersMuncher) September 28, 2016
Morning Consult: Hillary +23
YouGov: Hillary +27
CNN: Hillary +25
PPP: Hillary +11
But he cautions that there's really no reliable information on that yet. Most good polls are taken over a seven-day period, and it hasn't been seven days yet. By next week we'll have a better picture of what the first debate did to the race.
This is only personal intuition, so take it with the amount of salt it deserves. But I would be very surprised- and more disturbed about the sanity of the voters than worried, really- if the polls. when they come out, don't send Il Duce deep into denial mode and Hillary back into at least a clear lead.
