I have a different perspective. First, politicians should be confined to running the nation. This includes protecting the nation's borders, transportation, trade with other nations. This excludes fake political issues such as climate change and it also excludes personal matters such as abortion and where one chooses to send children to school.
I understand your position that abortion should be against the law, but I believe the better position is to take abortion completely outside the purview of government. Because...if we give government the authority to make abortion against the law, we have also given government the authority to place abortion within the law pronouncing it not only okay, but preferable in many cases. When government authority announces something is okay (such as abortion, no-fault divorce, etc.) it is fact that two-thirds of the population will go along with what authority says simply because it is the authority. This is what puts those of us who favor life in the minority--we lack authority.
Science confirms life begins at conception. When it is up to each individual to decide whether or not to take a life, most will not. Most will not torture another person either...unless, as Milgram's experiment showed years ago, someone in authority tells them that torturing was the right thing to do. Then, two-thirds of those will torture as directed.
My position is the government has no right to say abortion is okay, or for that matter, not okay. Abortion has nothing to do with protecting the nation's borders, regulating a nation's trade, or a nation's transportation. The Federal Government's purpose is to run the nation, not people's personal lives. There is no need for government to become involved in marriage, divorce, bearing/raising/schooling children as those are all personal, not national matters. I believe the better fight is to keep our national government out of ALL our personal matters, and for people to run their own personal lives according to their own faith, values, and ethics.
