I read your essay before I left for Tennessee for Christmas things. While the logic is there, I tend not to find intent and malice where simple incompetence is sufficient to explain the events.
I know that Democrats cheat in elections, especially in big cities. However, I don't think the networks are out to cheat. On the otehr hand, they are not out to do their job competently. A competent director would know that states like Florida and Indiana have multiple time zones, and therefore a chance of multiple poll closing times.
IMHO.
