Reaching out to religious voters, Democratic presidential candidate Barack Obama called for expanding US President George W. Bush's program steering federal social service dollars to religious groups and - in a move sure to cause controversy - supported some ability to hire and fire based on faith. Obama unveiled his approach to getting religious charities more involved in government anti-poverty programs during a tour and remarks Tuesday at Eastside Community Ministry, which provides food, clothes, youth ministry and other services. "The challenges we face today ... are simply too big for government to solve alone," Obama said. Obama's announcement came as part of a series of events leading up to Friday's patriotic Fourth of July holiday. The candidate spent Monday talking about his vision of patriotism in the battleground state of Missouri. By twinning that with Tuesday's talk about faith in another battleground state, he was attempting to settle debate in two key areas where his beliefs have come under question while also trying to make inroads with constituencies that are traditionally loyal to Republicans and oppose Obama on other grounds. But Obama's support for letting religious charities that receive federal funding consider religion in employment decisions could invite a protest from those in his own party who view such faith requirements as discrimination. Obama does not support requiring religious tests for recipients of aid nor using federal money to proselytize, according to a campaign fact sheet. He also only supports letting religious institutions hire and fire based on faith in the non-taxypayer funded portions of their activities, said a senior adviser to the campaign, who spoke on condition of anonymity to more freely describe the new policy. Rev. Barry Lynn, executive director of Americans United for Separation of Church and State, criticized Obama's proposed expansion of a program he said has undermined civil rights and civil liberties. "I am disappointed that any presidential candidate would want to continue a failed policy of the Bush administration," he said. "It ought to be shut down, not continued." John DiIulio, who in 2001 was director of Bush's White House Office of Faith-Based and Community Initiatives, said Obama's plan "reminds me of much that was best in both then vice president Al Gore's and then Texas governor George W. Bush's respective first speeches on the subject in 1999," according to a statement from the Obama campaign. Bush supports broader freedoms for taxpayer-funded religious charities, but he never got Congress to go along so he has conducted the program through administrative actions and executive orders. David Kuo, a conservative Christian who was deputy director of Bush's Office of Faith-Based and Community Initiatives until 2003 and later became a critic of Bush's commitment to the cause, said Obama's position on hiring has the potential to be a major "Sister Souljah moment" for his campaign. This is a reference to Bill Clinton's accusation in his 1992 presidential campaign that the hip hop artist incited violence against whites. Because Clinton said this before a black audience, it fed into an image of him as a bold politician who was willing to take risks and refused to pander. "This is a massive deal," said Kuo, who is not an Obama adviser or supporter but was contacted by the campaign to review the new plan. Obama proposes to elevate the program to a "moral center" of his administration, by renaming it the Council for Faith-Based and Neighborhood Partnerships, and changing training from occasional huge conferences to empowering larger religious charities to mentor smaller ones in their communities. Saying social service spending has been shortchanged under Bush, he also proposes a $500 million per year program to provide summer learning for 1 million poor children to help close achievement gaps with white and wealthier students. A campaign fact sheet said he would pay for it by better managing surplus federal properties, reducing growth in the federal travel budget and streamlining the federal procurement process. Like Bush, Obama was arguing that religious organizations can and should play a bigger role in serving the poor and meeting other social needs. But while Bush argued that the strength of religious charities lies primarily in shared religious identity between workers and recipients, Obama was to tout the benefits of their "bottom-up" approach. "Because they're so close to the people, they're well-placed to offer help," he said. Kuo called Obama's approach smart, impressive and well thought-out but took a wait-and-see attitude about whether it would deliver. "When it comes to promises to help the poor, promises are easy," said Kuo, who wrote a 2006 book describing his frustration at what he called Bush's lackluster enthusiasm for the program. "The question is commitment." Obama also talked bluntly about the genesis of his Christian faith in his work as a community organizer in Chicago, and its importance to him now. "In time, I came to see faith as being both a personal commitment to Christ and a commitment to my community; that while I could sit in church and pray all I want, I wouldn't be fulfilling God's will unless I went out and did the Lord's work," he said.
