White women vote Rep in a similar percentages as white men. According to the 2014 exit polls white men voted 64% to 33% for Reps and white women 56% to 42%.
A few comments:
Married white women vote similarly to white men, or at least they aren’t affected by the birth control/Sandra Fluke propaganda.
Unmarried women are still in the Dem pocket, even if they are white.
And, the 2014 exit polls you quoted are consistent with this, because even among white women, there is less support for the GOP than there is from white men. This is, or course, consistent with the married/unmarried divide noted above.
Finally, among this group, 2014 is so different from preceding years, that while it is hopeful, it may be premature to count on it going forward.
