Despite what they may think of their numbers, numerous polls are now showing that those Sanders supporters who will not support HRC are only about 10% of his base.

These are not insignificant numbers as every vote will count for something this year, but they are far from the huge group they wish to believe they are.  Their insistence on HRC begging them for support and kowtowing to them is less significant with each passing day.

Probably the best example of HRC's termination of surrender talks was the pick of Tim Kaine as her running mate.  If these Sanders holdouts do not see this as the poke in the eye that it is, and that the game is essentially over for them, they are not playing in the realm of reality.

In fact, while it would be great to have all the Sanders supporters on board, there are some who are at the extreme and would just as soon support Trump - these individuals were never part of the election calculus HRC used when determining her chances in the fall.
