Donald Trump believes he won the first presidential debate.
To be fair, the CNN poll does have some sampling issues, which have been fully acknowledged by CNN. However, the sampling is not so biased as to nullify its findings. Especially as Public Policy Polling, PredictWise, CBS News, Fox News, Politico, NBC News, ABC News, Trump surrogates and Donald Trump himself all present evidence as to his defeat.
Does Trump’s defeat mean anything for his chances come November? Probably not. But it was still a loss.
