I'm not a huge fan of Schaeffer, but that's mostly because of his presentation. I don't keep up with him, and some of what was posted above seems to hint that his theology is a bit funky now, though I'd have to look into it more to really give an opinion.
Unlike a lot of folks here, I usually agree with his politics, though I generally dislike political people, and he's certainly too politically-minded for my liking, lol.
