Charity Rorie, a mother of four, sat in her Mishawaka, Ind., kitchen, stunned that her name appeared on a 2008 Democratic presidential primary petition for then-candidate Barack Obama.

"That's not my signature," she told Fox News, saying her signature is "absolutely" a fake. She also said she was troubled someone forged both her signature and that of her husband, Jeff, and listed personal details such as their address and birthdays.

"It's scary," Rorie said. "It's shocking. It definitely is illegal. A lot of people have already lost faith in politics and the whole realm of politics, so that just solidifies all of our worries and concerns."
