Maria Ciano, a former Republican, was one of many women who emphasized President Obama's support for reproductive rights Tuesday night. "I still believe in small government but I no longer believe in the Republican party," she said. "They want to deny me the power to make the most personal decisions about my life. That's not small government. That's not the America I love."

Ciano, a 31-year-old stay-at-home mom in Westminster, Colo., also appeared in an Obama campaign video last month. But Ciano has actually been registered as a Democrat since 2006.

NARAL Pro-Choice President Nancy Keenan followed Ciano with a similar message. "Women in America cannot trust Mitt Romney to protect our health," said Keenan, who is stepping down at the end of the year. "We cannot trust Mitt Romney to respect our rights. "
