According to the New York Times, pro-life
The only problem was that Casey didn’t “reach out” to pro-life voters. He simply acknowledged his and Obama’s differing views on abortion in the following statement: “Barack Obama and I have an honest disagreement on the issue of abortion. But the fact that I'm speaking here is testament to Barack's ability to show respect for the views of people who may disagree with him.” That’s the only mention of abortion that appeared during the seven minute speech."
Casey could have reached out to pro-life voters, and illustrated Obama’s “respect for the views of people who may disagree with him” by discussing the new additions to the Democratic party platform in the abortion plank. The New York Times reported that “While it unequivocally endorses a woman’s right to abortion and the Roe v. Wade Supreme Court decision affirming it, the platform also includes calls for support for alternatives to abortion. Those measures include improved prenatal care, better financing for sex education, family planning and parenting classes, and more help for adoption.” Some of the alternatives to abortion, such as more help for adoption, truly is common ground in the battle over abortion.
But any other discussion would have taken away from the cheerleading performance to which the rest of Casey’s speech was devoted.
