Not any pre-millenialist/dispensationalist Christians, thankfully, we
don't want them. :) They all hang out with the neo-libs <i.e.
Boortz>. :)
I'm a premillenialist. Had to look it up to double check, though, because we don't use the term. There's only one kind of millenialist in my church. 
Gary North doesn't like us very much, because we don't share his vision of perfecting the world. Those of us who are libertarians are such because liberty is right, not because liberty is likely to flourish before Messiah comes. North calls us "pessimillenialists" for some reason.
But I think that the distribution of religion/atheism among libertarians roughly matches the population at large. Religion is mostly orthogonal to one's view of liberty. There might be fewer Muslims among us, and more atheists, than in the overall population. Just a guess.
