4. Gender gap huge in Massachusetts. The gender gap in Massachusetts is significant: 64 percent of female Massachusetts voters approve of President Obama's job performance, compared just 48 percent of men approving. Warren has a strong 52/18 fav/unfav with women, but a more middling 41/29 fav/unfav with men. Brown's favorability with men is 59/26, with his fav/unfav with women at 50/32. Warren will need to mobilize the women's vote, and she's already received support from high-profile allies, like EMILY's List.
5. Warren's got the Harvard vote locked up Most voters said they don't view Warren's academic background as a negative, but it's clear her base of support comes from the academy. Brown leads Warren among those with a high-school education or less (45 percent-24 percent), some college (45 percent-27 percent), college graduates (35 percent-32 percent), but Warren holds a significant 50 percent-28 percent edge among post-graduate students.
