Thousands of people from across the country gathered in Washington today for the annual March for Life, the world’s largest pro-life rally that in 2014 marks 41 years since the U.S. Supreme Court’s Roe v. Wade decision to lift restrictions on abortion. Public opinion on abortion has remained relatively stable during the past several years. In 2013, PRRI found Americans who believe abortion should be illegal in all or most cases are outnumbered by those who say it should be legal, 42 percent to 54 percent. And today, advocates for making abortion illegal are re-vamping their efforts to recruit and mobilize young people to carry on the cause. But how does the profile of younger Americans who oppose abortion compare with that of their older counterparts?
