While there are some Americans who are inclined to evaluate the moral, ethical, and medical legitimacy of abortion on a case-by-case basis, many others are strictly, unwaveringly pro-choice (favoring abortion rights) or pro-life (antiabortion). Over the last few decades, whether abortions should be legal at all--under any circumstances--has created a deep political rift across the United States. This book, which charts the shifts in interpretation of the U.S. Constitution on this matter, is a must-read for anyone hoping to understand where the nation and its laws have stood on the issue, its current state of play, and what the future of the abortion rights vs. right to life struggle may hold.
