UT's chart appears to come from
here, and shows the number of dues-paying members of the party.
You live in California according to your profile, Radar, so...
--14.6 million registered voters as of 1998
--87,183 registered Libertarians...I'm also assuming from 1998 (Source for this and the previous stat:
State of California)
--89,125 registered Libertarians as of Sept. 2002 (Source:
Libertarian Party of California)...a drop from a peak of almost 95,000 two years ago...and a drop from 92,000 in March, according to their recent counts.
That's a 6% drop since 2000...where's the increase?
