More than a couple. I'd guess at least a majority.
I am not trying to make any links but just listening to the news. The BTK killer was president of his church and described as a "holier than thou" type of person.
The evolution ping list has nearly 250 names now. I'm aware of three or four who have declared themselves to be atheists. The rest either: (a) don't discuss religious issues in science threads: (b) have declared that they see no conflict between religion (when properly understood) and evolution (this is the Pope's position); or (c) have said that they're theistic evolutionists. One has said he's a deist (maybe a couple of others have said that too).
