With all the talk about Roe v. Wade being overturned by a Roberts/Alito court I think it is easy to loose sight of the fact that the number of abortion performed in this country is a function of economics.
When the economy is expansive, as it was during Clinton's administration, unplanned pregnancies go down as young people are offered employment and reap the material benefits of our capitalists system. When the economy runs out of gas, and job growth stagnates, as it has under Bush, unplanned pregnancies and abortions go up.
So all this talk about Roe vs. Wade is kind of a side show. If you are "pro-life" and want fewer abortions, simply vote democratic and for economic policies that support broad based job growth, not the wealth hoarding policies of the republicans.
