Another chart:
Postgraduate men and women are Obama's greatest supporters among gender and educational groups. Obama fares especially well among women with postgraduate education (64%). Whereas postgraduates are the only educational group among men that shows at least 50% approval for Obama, all four educational groups among women do. Also, there are essentially no gender differences among those with a high school education or less, but notable gender gaps at higher education levels.
So after 1 year's experience of Obama, almost 2/3 of post-graduate women approve.
