I don’t the answer but there are 3 things to consider:
1) Chicago Tribune Sept 26th: “With two weeks left to register to vote, the number of people on Chicago’s voting rolls is about 225,000 less than it was by the time registration closed four years ago, election officials said today.”
2) Obama campaign officials threatened an NAACP official who is not backing Obama and he referred this to the police
3) Kevin DuJan of Hillbuzz lives in Chicago and says black pastors have been telling congregations to stay home and not vote. They are angry at Obama’s same-sex marriage policy and amnesty to illegals.
That is VERY interesting! One of the reasons Obama won last time was because of the record numbers of black voters who showed up. Reducing that number would be a real blow to his re-election chances.
