Here is a link to a good article by Melanie Israel (Heritage Foundation) on the recent report from the Guttmacher Institute about the declining rates of abortion in the US.
Here is a link to Michael New’s excellent analysis of the Guttmacher report. Here is New’s concluding paragraph–
“With state legislatures nationwide enacting increasingly stronger protections for mothers and babies, many are anticipating that the U.S. Supreme Court may soon rule on an abortion case and could even soon restore legal protection to millions of unborn children. That said, it is impossible to say which cases the Supreme Court will decide to hear and how they will decide any given case. That is why the long term decline in the U.S abortion rate is important. The growing pro-life American majority has had a strong record of progress during the past 40 years and regardless of how the U.S. Supreme Court rules on any future case — we have plenty of reasons to stay the course.”
