In this photo taken Thursday, March 22, 2012, Marisa Hannum, an assistant restaurant manager is seen at work in Reston, Va. As a married woman, Hannum had her family's conservatism on her mind when she backed Republicans in the two most recent presidential elections. Now divorced, Hannum is putting her own interests first as she weighs whether to back President Barack Obama or his Republican challenger. Unmarried women are emerging as a critical constituency in an election year focusing heavily on social issues and the economy. Democrats are trying to energize them while Republicans work to peel them away. (AP Photo/Carolyn Kaster)
