As I'm sure you're aware, there's a large divide over abortion. It usually does fall along political ideologies. Not always, but usually.
I never understood why politics, as in political party persuasion, should enter into this. Ask any group of random people to draw a line for when they think a healthy mother, aborting a healthy baby is taking the life of an actual baby, and is no longer merely the mother making "a choice." Ask a hundred people to draw you that line, and you will get dozens of varying answers.
It's not even a religion issue. Plenty of people of all faiths, and even agnostics and atheists oppose abortion of a healthy baby by a healthy mother, after a certain number of weeks.
