Sen. Bob Casey (D-PA), the great hope of the "pro-life" revival in the Democratic Party, is set to endorse Sen. Barack Obama. Casey's decision follows on the heels of another Catholic pro-abort, Gov. Bill Richardson (NM), to choose Obama over Clinton.

If I had to decide who was more pro-abortion, Obama or Clinton, it would be difficult since they each have a 100% NARAL rating. I guess I would nod toward Obama since he described his biggest "mistake" in politics as voting to allow the parents of Teri Schiavo to have their daughter's case reviewed in court.

I suppose Prof. Doug Kmiec, who also endorsed Obama, will applaud the decision of Sen. Casey, and offer to join Casey and Obama on their bus trip across Pennsylvania.

They can write"Pro-Life Catholics for Obama" across the side of the bus! That might provoke some laughter from even the staunchest of Pennsylvanians.
