Absolute nonsense. The baby boomer generation was the zenith for the "pro choicers', their progeny are much more pro life. So hearts and minds have been changed.
Today's 18-25 year olds are more socially liberal than any other age group. And yes, unwanted pregnancies and teen pregnancies have been dropping for years and that accounts for the drop in the number of abortions. Do you really believe we will reach a day where we can outlaw all abortions in all states?
