Well, yes. But that IS what tends to happen to large-scale left-wing Christian organizations in this country (the Jesus People, say.) I'd definitely prefer a left-wing Christian party (one that I'd actually vote for); but I have a feeling that if one were created, it would a) be essentially indistinguishable from the Democratic party (except in rhetoric), and b) it would end up getting coopted by anti-abortion evangelicals and Catholics. So I'm just being a political realist.
