American voters to have libertarian-leaning views. There is another measure the party uses internally as well. Since its founding, the party has apportioned delegate seats to its national convention based on the number of members in each state who have paid minimum dues (with additional delegates given to state affiliates for good performance in winning more votes than normal for the party's presidential candidate). This is the most-used number by party activists. As of December 2017, the Libertarian Party reported that there were 14,445 donating members. Historically, dues were $15 throughout the 1980s and in 1991 they were increased to $25. Between February 1, 2006, and the close of the 2006 Libertarian party convention on May 31, 2006, dues were set to $0. However, the change to $0 dues was controversial and was de facto reversed by the 2006 Libertarian National Convention in Portland, Oregon, at which the members re-established a basic $25 dues category (now called Sustaining membership) and further added a requirement that all National Committee officers must henceforth be at least sustaining members (which was not required prior to the convention). Registered voters Ballot access expert and editor of Ballot Access News Richard Winger periodically compiles and analyzes voter registration statistics as reported by state voter agencies and he reports that as of early 2020 the party ranked third in voter registration nationally with 693,634 .

Since the party's creation, 10 Libertarians have been elected to state legislatures and some other state legislators have switched parties after being originally elected as Republicans or Democrats. The most recent Libertarian candidate elected to a state legislature was Marshall Burt to the Wyoming House of Representatives in 2020. The party elected multiple legislators in New Hampshire during the 1990s as well as in Alaska during the 1980s. One of the party's Alaska state legislators, Andre Marrou was nominated for vice president in 1988 and for president in 1992. As of 2017, there were 168 Libertarians holding elected office: 58 of them partisan offices and 110 of them non-partisan offices. In addition, some party members, who were elected to public office on other party lines, explicitly retained their Libertarian Party membership and these include former Representative Ron Paul, who has repeatedly stated that he remains a life member of the Libertarian Party.
