All right, Go Kate Michelman Go!
In all fairness, I believe Junior Casey is pro-life. A similiar thing happened in the IL-03. Bill Lipinski Sr. of the Il-03 retired in 2004. He cleared the field to enable his son, junior to take the seat. I initially suspicious of junior's pro-life convictions. Considering the demographics of the district, you don't need to be pro-life to win. However since serving in Congress, Lipinksi Jr. has voted pro-life including against embryonic stemm cell research.
True, Dan Lipinski's voting record has been 100% pro-life so far. http://www.capwiz.com/nrlc/bio/keyvotes/?id=151645
But Bob Casey, Jr. has made some statements that made me question whether he was truly pro-life, and his decision to wait until Ed Rendell to support Judge Alito to do likewise makes me doubt that he would ever go out on a limb for pro-life causes.
