A CNN/ORC poll taken after the first presidential debate found that 62% of voters who had watched the head-to-head thought that Hillary Clinton came out on top, with just 27% giving it to Donald Trump.

This is based on interviews with 521 registered voters chosen as part of a random national sample. However, only 26% identified themselves as Republicans while 41% identified themselves as Democrats.

An informal CNBC poll on its website found that 61% of people thought that Donald Trump won while 39% went for Hillary Clinton, but as CNBC itself points out, the poll is not scientific – anyone, including people outside the United States, appears to be able to vote.

A post-debate survey by Public Policy Polling of 1,002 debate-watchers found that 51% of national voters thought Hillary Clinton had won, with 40% choosing Donald Trump and 9% undecided.
