Black Churches' Bad Tradeoff

In trying to figure why so many black pastors are adopting issues and causes dear to white evangelicals, I realized that, more often than not, these black pastors hope to score points with the Bush administration and, therefore, increase their chances of winning big bucks from the president's "faith-based initiatives" program.
With their own church-sponsored social programs costing large sums, some black ministers are lining up for a federal handout. For his part, Bush, along with other Republicans, gets the conservative black Christian vote.
What is the tradeoff in this scenario? What is the cost to the black church's traditional mission and its viability in the communities it serves?
