Is there room in the Obama governing coalition for pro-life Democrats? The president personally provided the answer to that question, a resounding yes, in his speech at the University of Notre Dame last month. Others are not so sure.

The issue arises most recently with the recent appointment of Alexia Kelley as director of Faith-based and Neighborhood Partnerships at the Department of Health and Human Services.

Kelley is the founder of Catholics in Alliance for the Common Good, a Washington-based group that “promotes increased awareness of Catholic social teaching through the media and provides opportunities for Catholics and citizens of goodwill to advance the common good in the public square.”

Catholics in Alliance, from its outset, took a decidedly “seamless garment” bent to the issues. From its Web site: “We support a consistent culture of life that includes protections for unborn children; implementation of social, economic and material supports for pregnant women and vulnerable families; and protections for children from abuse, poverty and neglect.”

Catholics in Alliance was among the groups in the 2008 campaign that successfully broadened the Catholic political playing field, which redounded to the benefit of Democrats in key states such as Ohio. Obama won the overall Catholic vote and drew nearly even with John McCain among those -- a targeted constituency for Republicans -- who attend Mass on a weekly or more frequent basis.

But election coalitions, where most everyone is welcome in the interest of defeating the opponent, are different from governing coalitions, where actual programs and policies are implemented. Once united in their support of candidate or cause, interest groups fray as the poetry of politics is translated into the prose of governance.

So today we have Catholics for Choice, a Washington-based organization that favors abortion rights, condemning Kelley’s appointment. “In appointing an anti-choice advocate to a key position in Health and Human Services we are seeing crucial principles abandoned -- principles upon which so many men and women rely to lead healthy lives,” said Jon O’Brien, the group’s president. Kelley, says O’Brien, is an “anti-choice advocate” because she favors programs that would reduce the need for abortion while abandoning the “principle” of “support for abortion rights.” Stalinists versus Trotskyites was less arcane.
