I researched Beau Biden a little. He was supposed to be coronated as senator to replace his father after he got back from Afghanistan. He decided not to run. He prosecuted some abortion clinics ala Gosnell. He was a practicing RC. So did he also tell his dad to be pro life? I am totally speculating. Has Joe said anything about Planned Parenthood? I did a quick search and the stories I found were prior to Beau’s death.
At this point in time a person cannot be a democrat and be "prolife. Being a Democrat means you worship death and sacrifice your children like the ancients did to Ba'al and Molek. It is therefore impossible for Beau Biden to have been an actual Christian if he was a democrat.
