Casey, Sr. was a genuine pro-lifer. I would have gladly voted for him both times he ran for Governor (especially in 1990).
What do you mean by "genuine pro-lifer"?
Casey, Sr. signed a bill placing restrictions on abortion called the ''Pennsylvania Abortion Control Act'' in 1989, and later defended the law against Planned Parenthood at the Supreme Court. He tried to give a pro-life speech at the 1992 Democratic National Convention, but was denied a speaking slot.
Casey, Jr. claims to be pro-life, but usually sides with Planned Parenthood and NARAL when it comes time to vote on the issue.
