George Weigel has provided a detailed rebuttal to recent arguments by some avowedly pro-life Catholics that it’s OK to vote for Sen. Barack Obama.

In a Newsweek commentary posted Oct. 14, the papal biographer and syndicated columnist critiques arguments advanced by three prominent Obama apologists: law professors Doug Kmiec, Nicholas Cafardi and Cathleen Kaveny.

Space doesn’t allow us to do justice to all of Weigel’s comprehensive dismantling of the trio’s arguments about why it’s morally acceptable to vote for Obama despite his unswerving commitment to the expansion of abortion rights — and his repeated campaign promises to appoint only Supreme Court judges who will support the 1973 Roe v. Wade decision that legalized abortion.

But here’s one of the more telling passages from the Newsweek article:

“Another line of critique against the pro-life, pro-Catholic Obama activists has been mounted by, among others, Cardinal Francis George of Chicago, who holds a doctorate in political philosophy and currently serves as president of the U.S. bishops’ conference,” Weigel writes. “In a September letter to the people of the Archdiocese of Chicago, the cardinal laid down what he described as a basic principle of justice: in a just society, innocent human life, especially when incapable of self-defense, deserves the protection of the laws. No one who denies that, the cardinal argued, can claim to be advancing the common good.”

Sums up Weigel, “And, as Roe vs. Wade does indeed deny the protection of the laws to the unborn, no one can, with any moral or logical consistence, claim to support both Roe vs. Wade and the common good. It’s one or the other.”
