From an interview BeliefNet's Dan Gilgoff did with Rick Warren:
Before last night, McCain had been widely criticized by Christian activists for keeping mum about his faith and about values issues like abortion and marriage Last night seemed to change that. How much headway did McCain make among skeptical evangelicals? I'm a pastor, I'm not a prophet, so I would not predict how evangelicals are going to vote. I will tell you they're not monolith. That's a big myth. They're going to make up their minds based on the hierarchy of their values. For many evangelicals, of course, if they believe that life begins at conception, that's a deal breaker for a lot of people. If they think that life begins at conception, then that means that there are 40 million Americans who are not here [because they were aborted] that could have voted. They would call that a holocaust and for them it would like if I'm Jewish and a Holocaust denier is running for office. I don't care how right he is on everything else, it's a deal breaker for me. I'm not going to vote for a Holocaust denier[...] Then it sounds like it would be unconscionable for an evangelical to vote for a pro-choice candidate like Obama. Well, we're going to see what happens. All I can say is you'll see what happens.
