Here are a couple of interesting data points from 538.com. On the left, you can see where Hillary Clinton is picking up votes compared to Barack Obama in 2012. Not from blue states or swing states, which are polling about the same as they did in the last election, but in red states. She’s picked up a whopping 8.4 points from folks in red states who would presumably vote Republican in normal times, but just can’t stomach Donald Trump.
On the right, you can see the cumulative total winning margin in CNN’s post-debate instant polls since 1992. Clinton posted the best record of any candidate ever. Alternatively, you could say that Donald Trump posted the worst record of any candidate ever. It’s not clear which is the more appropriate description, but even if you think Trump’s meltdowns were the decisive turning points, Clinton employed a brilliant strategy for baiting Trump into losing his shit in front of a hundred million viewers. Either way, Hillary Clinton is one of the greatest presidential debaters of recent history.
