WASHINGTON -- A prominent evangelical Christian said Friday that if Rick Santorum continues to surge in the polls and does well in New Hampshire and South Carolina, Christian leaders are planning to ask Newt Gingrich and Rick Perry to drop out and get behind the former Pennsylvania senator. "There is real concern that [Mitt] Romney will win without having to face one concentrated effort of a conservative challenger," Richard Land, one of the most well-known Southern Baptist leaders in the nation, told MSNBC's Andrea Mitchell.
