As Wednesday's March for Life demonstrated, abortion opponents have been buoyed of late by a string of victories across the country in states where Republicans control both the state legislature and governorship.

Both abortion rights advocates and foes agree that those seeking to curtail access to the procedure are winning. Fifty-three abortion restrictions were enacted into law in 2013, according to NARAL Pro-Choice America, and the states where abortion opponents have unified control outnumber those dominated by abortion rights proponents by a ratio of 3 to 1. As a result, a slew of new requirements — on questions ranging from the point of a fetus's viability to whether a women seeking an abortion should be required to see an ultrasound before undergoing the procedure — are making it into law.

"People are more confident about being pro-life," she said in an interview, after attending the rally. "They're not ashamed of being on the other side."
