Obama and Mitt Romney are engaged in an all-out effort to court women in the campaigns closing weeks, knowing that women could help determine the winner in a series of toss-up states. Women have emerged as the pivotal voting bloc in the aftermath of the second presidential debate, where Obama and Romney sparred over contraceptives and pay inequality. (AP Photo/Carolyn Kaster, File)
