Dr. Michael New, in an opinion piece first appearing at Roll Call, and then run by LifeNews.com, cites AUL statistics:
Americans United for Life reports that since 1992, the number of states with parental involvement laws has increased from 20 to 38. The number of states with informed consent laws has increased from 18 to 33. The number of states with abortion clinic regulations has increased from 21 to 30. More importantly, after Casey, many states strengthened existing restrictions. In particular, several states improved their informed consent laws by including more information about health risks, fetal development and sources of support for single mothers.
