From the link you posted: “Paul is pro-life. However, Paul holds that the United States Constitution does not grant the federal government any authority to legalize or ban abortion.”
That is the equivalent of saying that one’s rights are a function of the state in which one happens to be. Cross a state line and your rights can change. Do you find that the be the position of a ‘true conservative’?
Did you read the The Sanctity of Life Act?
It says that unborn babies will have the same rights as all human beings.
