Obama has 95% of blacks and at worst 70% of white women. That’s at least 42% of the total electorate locked up in his favor and campaign fear-mongering will keep it that way. Not including Dem voter fraud and intimidation, he just needs to win over 8-9% of the remainder—which includes other minorities, x-gens/millenials and homo/metrosexual white males. Seems like that’s enough right there.
Everyone always knew that black people were a lock for Democrats. They are kept, at great pains, on the plantation.
Women, perhaps another story. As more women feel a need to have a presence in the workplace, a business minded Mitt may start to look better than a business sabotaging Barack. Also, the Democrats have already shot themselves in the foot with remarks about Mrs. Romney which garnered more sympathy for her than disdain for Mitt’s supposed “anti woman” sentiments.
