But from 2008 to 2010, when control of Congress was at stake, the DNC cut its faith outreach staffing from more than six people to one part-timer, according to The Washington Post.
Harkins, appointed last October, is the senior pastor at the historic Nineteenth Street Baptist Church in Washington and has held many leadership positions, including as a past board member of the National Association of Evangelicals. He has little political or campaign experience.
Until last month, the Obama re-election campaign hadn't named a national director for religious outreach. Until he joined the campaign, 24-year-old Michael Wear was an executive assistant in the Faith-Based and Neighborhood Partnerships office.
Harkins said in a telephone interview that he brings to the job relationships built over years with clergy nationwide and noted that he works as part of a DNC team conducting voter outreach. The Obama campaign would not discuss specifics of its outreach, citing a policy of not disclosing staff numbers or strategy, but said efforts to reach religious voters have been part of the Operation Vote initiative targeting different constituencies.
"I don't think there's been any evidence of a deficit," Harkins said. "If there's a change we're seeking, it's to be broader, more robust, reaching a broader section of the faith community."
The issue is arising at a particularly sensitive time when Obama's critics are accusing him of enacting policies that are "choking" religious groups.
Catholic bishops have filed a dozen lawsuits nationwide challenging a Department of Health and Human Services mandate that most employers, including religious groups, provide insurance that covers birth control. The president has offered to shift the cost to insurance companies. But Catholic prelates said the accommodation still links the church to a practice that violates their beliefs.
Recently, evangelical, Orthodox Jewish, Catholic and Mormon leaders helped form in every state a new network of caucuses dedicated to religious liberty, with the birth control mandate as their initial focus.
The advocacy group Conscience Cause formed in February to rescind or revise the birth control mandate. The organization's board includes Jim Nicholson, the former U.S. ambassador to the Vatican under President George W. Bush, and Republican strategists Mary Matalin and Ed Gillespie. Gillespie is an adviser to the Romney campaign.
But some of the president's traditional allies are among the critics.
The Tablet, the British Catholic newsweekly read widely by American Catholic liberals, said in a recent editorial that Obama "has perhaps been misled into thinking that the widespread dissent to these teachings among Catholics means he can disregard the views of the bishops without having to pay an electoral penalty."
Four years ago, Douglas Kmiec, an anti-abortion former official in the Reagan administration, backed Obama, drawing widespread condemnation from fellow conservative Catholics. In a column last month in the liberal U.S. newspaper the National Catholic Reporter, Kmiec praised the University of Notre Dame for suing the administration over the narrow religious exemption in the birth control rule. In 2009, Notre Dame withstood intense criticism from American bishops and honored Obama, despite the president's support for abortion rights.
"Unwittingly, perhaps, the president has allowed his appointees to drift into the secular lane and stay there," Kmiec wrote.
Catholics, who comprised about one-quarter of the electorate in 2008, haven't voted in a bloc for decades, but the candidate who wins the most Catholic votes usually wins the election.
Some Democrats see no problem with consigning faith outreach to the sidelines. They argue that attempts to please moderate and conservative religious groups have kept Obama from fully enacting some policies important to party members. Among these critics are Democrats who consider church leaders' complaints about the scope of the birth control mandate an attempt to extend legal privileges to religious groups at the expense of women.
