The self-identified pro-life case for Obama is subject to scrutiny here – by Ryan T. Anderson and Sherif Gergis.
It’s tight. It’s one-stop shopping, with links to other supporting pieces.
In addition, John Breen has several posts at MOJ on the subject. Just go here and scroll here and around.
And then this – at HotAir, from Ed Morrissey and The Anchoress (Elizabeth Scalia.)

Even beyond this, though, consider why the Church supports social-justice issues.  Our faith does not emphasize fighting poverty and oppression as mere Boy Scout merit badges, or to give Catholics something to do on the weekends.  The emphasis on social justice springs from the foundational belief that all human life is sacred, anointed by God for His purposes, and not ours.  The need for social justice is for us to recognize the spark of divinity in all of us.
What does abortion says about human life?  It reduces it to commodity, and values it based on convenience.  If that is what we think about human life, then that rejects the entire idea that God created humankind at all, let alone for any divine purpose.  Without that fundamental understanding of the faith, then all kinds of horrors become possible — abortion, euthanasia, genocide on massive scales, war for acquisition, and the exploitation of the poor.
Why care about the poor if humans have no divine purpose?  If we can kill millions of our offspring without a second thought, why not leave the poor to their own devices?   Abortion represents the ultimate rejection of God and God’s plan.
And bear in mind that Barack Obama is no moderate on abortion.  The FOCA will federalize the question of abortion with the specific intent of striking down every moderating state law concerning abortion: parental notification, waiting periods, term limitations, and information requirements will end with its passage.  It will also re-impose federal subsidies of abortions by repealing the Hyde Amendment, forcing taxpayers — including Catholics — to pay for the abortions of others.
The question, then, boils down to one of reason: does your reason tell you that Sen. Barack Obama – a mere human being with a thin resume and a seeming propensity for shutting down, punishing, intimidating or otherwise harassing those who do not fall in line (through the force of government, if possible) – is going to heal the human heart through his social programs and his redistributionism?
Matters of the heart are never resolved through worldly machinations. More importantly, to expect a human man – who because he is human carries within him another broken, imperfect heart – to successfully, righteously and most of all disinterestedly resolve issues which have tested mankind for thousands of years is to assign onto him inhuman abilities; this smacks of idolatry and thus flies in the first and most fundamental priority of a believer: to have no gods before the One, the Creator.
Catholicism does not reject reason for faith but demands integration of the two, and prayerful discernment, before taking any action.
One’s vote should come after weighing reason.
Reason tells us that a human fetus is a human being and as such deserves inclusion into the whole notion of “human rights.” A candidate with consistent notions of human rights should be able to acknowledge that.
Reason tells us that an “abortion reduction agenda” is inconsistent with the stated priority of signing into law a sweeping, tax-payer funded abortion-rights legislation.
Reason insists that an ideology embracing the idea of genocide – whether that means eliminating people conceived with an extra chromosome or of wiping a sovereign nation off the map – is a warped ideology that is inconsistent with a commitment to human rights. Reason wonders why an electorate is not permitted to hear what a presumptive president might say to some such ideologues, and reason becomes very uncomfortable.
Reason tells us that one human man will not eradicate poverty. One human man will not eradicate war. One human man will not distribute justice to the nations. History is pockmarked with the graves of those slaughtered to the ambitions of human men who have tried to perfect and justify the world, according to their lights.
Barack Obama – inconsistent though he be – is no Hitler, or a Stalin or a Pol Pot. However, developing a fanciful notion of Obama’s ability to do and be more than man has ever done or been before – based on nothing more than a bit of charisma and an highly overprotective press – is to surrender, rather than apply, one’s use of reason.
Tomorrow is Election Day. By all means, each of us must vote for the candidates we believe will best serve the nation. ACORN aside, you only get one vote. Before your pull the lever, take some time to consider whether you have really applied your God-given gift of reason to it. And as Catholics, consider carefully which candidate best fits within our view of human life and God’s purpose for it.

Agreed.
