I don't even want to think of the repercussions this would bring. Warren has already fooled millions, this would just bring the political situation to a crisis, if he could convince enough of the Religious Right to follow him. He would really be asking for an all out war in the church community.
Will he actually practice what he preaches in regard to inclusion of all political persuasions and attempt to reach out substantially to conservatives, or will he allow himself to be seduced by the money and the fame of being in the media spotlight, and continue to parrot the leftist party line, which will be the price of keeping those things?
He's already had one test, with Joe Farah (who I don't have much use for most of the time myself, but in this case he's right on) calling him out on one blatant lie; unfortunately, his response, calling Farah an agent of Satan, constituted a failure of the test, and doesn't bode well for the future.
Unfortunately many evangelicals are suckers for conmen. With a Bible in their hand, and heavy reliance on out of context scripture, with the name of Jesus continually invoked you can rake in serious bucks.
And reassure your congregation that "works" don't count....all you have to do is mouth "I accept Jesus as my savior" and you're assured of your personal salvation.
