Pennsylvania attorney Maria Wing, 28, says it's becoming increasingly difficult to make it on one income. Program note: See Randi’s report on the influence of unmarried women on the election on AC360° tonight at 10pm ET. Randi Kaye 360° Correspondent   If only the candidates had the luxury of time.. to meet with unmarried women in Pennsylvania and hear their plea. I had the chance to do that last week and it was such an eye-opener. First of all, you should know, a quarter of all eligible voters in Pennsylvania are unmarried women. One in four voters! Unmarried women are the ultimate economy voter. Their average income is about $30,000 a year. Twenty percent of them are single moms and they tend to vote Democratic, which makes them a virtual “gold mine” for Democratic candidates. When I suggested to the women I interviewed that they are a gold mine, they chuckled. They certainly don’t feel like one. They are struggling and they’re not sure if the candidates are noticing. One of the women, Maria Wing, a lawyer in Philadelphia, told me about one third of her income goes to student loans and another third to house payments. She says, “after Uncle Sam gets paid, and Fannie Mae gets paid, and housing expenses get paid, mama only has a couple hundred dollars to go out. I’m still driving my beat up Sentra from law school.” Maria was one of four unmarried women that we interviewed. Two are voting for Barack Obama and two are voting for Hillary Clinton. They disagreed on some policy issues but they all agreed their voting bloc needs help. They care about real-life economic needs: healthcare, childcare, raising the minimum wage, and equal pay. They make about 56 cents on the dollar compared to men. Married women earn about 77 cents on that same dollar. Unmarried women are three times more likely than married women to lack healthcare. Unmarried women in college are having a tough time paying for it, and some are already worried about healthcare costs once they graduate. Home prices are dropping and they are watching their investments slip away. No wonder this year they want to make sure their voices are heard. Unlike in 2006, when nearly one million unmarried women in Pennsylvania stayed home on Election Day, this year many say they will hit the polls. Around the country, unmarried women have been voting in the primaries at historic levels, so Pennsylvania is expecting the same thing. The campaigns sure hope they turn out and have been aggressively targeting single women. Even hiring them to work on the campaigns. If they continue to mobilize as they have been, do you think unmarried really have the power to determine the next president? A recent study shows 58 percent of single women in Pennsylvania consider themselves Democrats, compared to just 18 percent as Republicans. In Pennsylvania, they are split between Clinton and Obama. Clinton has a slight edge with the group, 50 to 48 percent. The head of Women’s Voices, Women Vote Action Fund predicts “unmarried women will be to progressives what evangelicals were to conservatives and their participation rate and their policy agenda will be heard and will determine the future of this country.” Do you think the candidates are listening?   Less
