The religious philosophy of the Democrats is rooted in the Talmud of Judaism. The religious philosophy of the Republicans is rooted in the Bible.
Concerning abortion, this is a quote from Judy Rabinowitz published in The Jewish Voice.
"In Jewish law, an unborn fetus is not considered a person, a Nephesh or a soul until it has been born. Religious zealots who have coined the term Pro-life are really Pro-fetus. Their strategy is to band any type of late term abortion by claiming that it constitutes murder."
However, the bible doesn't agree with this statement and says, "Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee." Jeremiah 1:5
