Hadley Arkes, Ney Professor of American Institutions at Amherst College and one of the sharpest moral philosophers of our time, has a new article in First Things on Abortion Politics 2008.
His thesis: "The nomination and election of Rudy Giuliani would mark the end of the Republican party as the pro-life party in our politics. And that would be the case regardless of whether pro-lifers respond to his nomination by refusing to vote for Giuliani, forming a third party, or folding themselves into a coalition that succeeds in electing Giuliani."
Most interesting suggestion: "It is conceivable, then, that from the standpoint of the pro-lifers it might be better to lose to Hillary Clinton than to win with Rudy Giuliani. . . . The Republicans might be diminished, but they would be essentially intact as a pro-life party; and, when the electoral winds shift again, they have a chance of coming back with their character intact."
But the conclusion (pass the smelling salts to Joe Carter): "Faced then with the possibility of a Democratic presidency determined to weave the ethic of abortion rights more firmly into our law and to have its judges install same-sex marriage, a Giuliani candidacy could offer some slender grounds of hope. Under those conditions, I might bite my lip, vote for him, and indulge those hopes. But they would be the hopes of the supplicants. And they will be affected at every point by the awareness of just who has the upper hand, and just who, in this party newly reshaped, does not matter all that much."
