Maybe there is a pro-life surge?
I mean, I feel like you're joking but the country's shift in poll numbers toward being pro-life kind of matches that graph, doesn't it? Like two thirds of Americans were pro-choice in the mid-'90s.
I think things are pretty steady with that issue now and it seems exit polls are actually going the other direction but I will agree with you that in the 90s, there seemed to be a lot of pro-choice, pro-deathpenalty people. Maybe it was because Bill Clinton was really good at triangulating between law and order and social liberalism.
