This is one of those issues that shows the deep schizophrenia of the American Right. On one side, Libertarians should be arguing for the mother's personal right to choose; if they're not, they aren't really holding true to the Libertarian idea. On the other side, you have the Conservative Christians who oppose abortion on the grounds that killing is wrong (and yet fully support war, because obviously killing babies is wrong but killing young men gets a free pass from God because we're always on the side of good and thus it's always a noble sacrifice made by a willing young man to damage evil in some form.)
Because clearly Exodus 21:22-24 doesn't at all give a clear Biblical statement that causing a miscarriage (in other words, killing a baby) is only worthy of a monetary fine, whereas actually committing murder at that time and place was grounds for getting murdered yourself. And if you trace back the history of the "life begins at conception" concept in America, it only goes back as far as Jerry Falwell in the 1980s. Before that most Protestants were pro-choice. But forget history and what the Bible actually says. But then, I'm off on a tangent. The point here is that there is no consensus about abortion -- not across the aisle, not even just on the right side of the aisle. Trying to pretend that there is a monolithic entity "The Right" (or a corresponding entity "The Left") that can be attacked as a whole on this issue is dumb.
