Sarah Palin had dinner with Rev. Billy Graham at his Montreat home Sunday, making a surprise stop on her national book tour. The former Alaska governor and 2008 Republican vice presidential nominee was greeted by Franklin Graham and a crowd of supporters when her plane touched down in rainy Asheville. Palin said the visit was about matters of faith, not her political future. Billy Graham has counseled and advised every president since Dwight D. Eisenhower. On Monday, Palin will sign copies of her memoir, “Going Rogue: An American Life,” at Fort Bragg. The book signing goes from 11 a.m. to 2 p.m.
