Hillary Clinton says she isn't a natural politician and is proving it.
Within the space of 24 hours, Hillary has said she will put coal miners out of work and also said no Americans died in Libya (as Emily has discussed here).
Let's keep in mind that these statements were not made during debates with Bernie Sanders. These were made during town hall meetings on friendly networks (CNN & MSNBC).
At this rate, she might have stop doing town hall meetings before she does any further damage to herself. By night's end, her delegate count could be sufficient that Bernie Sanders can't mathematically catch up. In which case, why put herself in those situations?
