I've been a subscriber to Liberty since the first issue, and I miss those early days when the subscriber survey showed more than 90% of the subscribers were atheists. It's my perception that the religious-right subscribers have increased, and it seems rare that an issue comes out without a cranky letter from someone like Strain, whose brand of liberty doesn't appear very libertarian.
[Correction to the above: The 1988 Liberty poll did show a majority (74%) of subscribers to be atheists, but it was not "over 90%." In the 1998 followup poll, it was still a majority (62%), but a smaller one. -jjl, note added 2005-01-07. See the poll results here. -jjl]
