Comment: Xavier:  Your position regarding the primary election is simply too silly to merit a response.  

However, regarding the polls, please note the one you mention was on June 22, 2016.  Mr. Sanders endorsed Ms Clinton on July 12, 2016.  It's hardly surprising that the numbers changed significantly with that endorsement.  The 85 to 90% figure is accurate. It's not necessary to "cherry pick" to get those numbers.
