Tim Wildmon, who runs the American Family Assn., one of the most generous underwriters of Christian conservative activism, predicted that evangelicals in 2012 will match the fervency of the Ronald Reagan era — in large part because so many pastors are prodding their flocks to the polls."They're going to be telling their parishioners to get registered and to make sure to go vote," he said. "I think it's huge."Boosting the movement are veteran figures such as Ralph Reed, former head of the Christian Coalition. His new organization, Faith & Freedom Coalition , is developing a list of Christian voters in key states, a tool it used to reach thousands of voters in Wisconsin's recent recall elections.New players are even more ambitious. United in Purpose, financed by an anonymous group of Silicon Valley venture capitalists, aims to register 5 million conservative Christians to vote . The organization boasts a sophisticated database that identifies millions of unregistered evangelical and born-again Christian voters around the country.
