Great suggestion, Mary. In 2013, Common Ground was described by the Washington Post as "a loose coalition of religious leaders who defined themselves as pro-life were standing shoulder-to-shoulder with abortion rights advocates. By 'setting aside efforts to outlaw abortion' and instead turning the focus to reducing abortions—through limiting unintended pregnancies and supporting pregnant women—participants hoped to jumpstart a less rancorous discussion that could unite unlikely allies."

The Common Ground coalition faltered for two reasons: 1. The National Right to Life Committee (which should get an award for driving its own cause into the ground) because they would not accept the compromise of abortion reduction; 2. the failure to include contraception as a cornerstone of abortion reduction—although there were a few isolated victories in that front; and 3. the perception that Obama took the cause on and then walked away. 

Lots to ponder.
