This news story reveals that the West Virginia Secretary of State tallies the number of registrants in all parties now, even the unqualified ones.  The Libertarian Party has 1,300 registered members, even though it was only a ballot-qualified party during the period November 1996 through November 2000.  The Constitution Party has 99 registered members, counting the obvious misspellings of “Constitution.”  Thanks to Jeff Becker for the link.
