Christian conservatives who blame “moral depravity” for everything from the recession to terrorism are converging on Philadelphia for a rally they hope will spark a religious revival as Election Day nears.

Called “America for Jesus 2012,” the prayer assembly on Independence Mall is attracting support across a spectrum of Protestant clergy and activists. Among the scheduled speakers are religious broadcaster Pat Robertson and Family Research Council president Tony Perkins, along with preachers such as Cindy Jacobs of Generals International ministry who say they’re prophets with a direct line to God. Many backers had also endorsed “The Response,” the prayer rally hosted last year by Texas Gov. Rick Perry just before he entered the GOP presidential primary.
