Hillary may have well greased the palms, but they took the money and sat on their arses because they didn’t really like her enough to do the job right.
I think it is a bit more sophisticated than that. The “community organizers” could find themselves being replaced if they don’t bring the votes. “Community organizers” are a dime a dozen.
I wonder if they asked for more money and Hillary thought she couldn’t lose so she balked.
