Hillary Clinton received a standing ovation at one of the nation's most influential evangelical churches after addressing its "Global Summit on AIDS and the Church." If the Democratic presidential frontrunner's aim was to make inroads into the electorate's heavily Republican evangelical community, her appearance at Saddleback Church with pastor and "The Purpose Driven Life" author Rick Warren apparently didn't hurt.
