Abortion is actually one of the few "social" issues that the American public isn't getting that much more liberal on, compared to gay issues, marijuana legalization, etc.
opinions on abortion have been fairly static since polling on the issue began. Opinions on gay issues however, have undergone an almost sisemic shift in the last 10-15 years. Imagine how badly Prop 8 would have been defeated 10 or even 5 years ago. I'm ready to predict that a majority of Americans will support same-sex marriage by the year 2030, if not sooner.
