Billy Graham doesn't see that as his job. He only seeks to bring people closer to God, which is something Dobson cannot claim. And I say that as a Catholic who doesn't have a horse in the Graham/dobson race.
I am not influenced by either 'man'. However, given the public proclamations by both at least Dobson does stay on the RIGHT side of the political fence. Graham has always been on the LEFT even with his come to Jesus events.
