On May 1, the Nevada Secretary of State released new registration data. The state releases this data every month. See it here.
The Libertarian Party is ballot-qualified only because its registration is above 1% of the number of registered voters. In November 2018 it did not meet the alternate 1% vote test. The registration data released on May 1, 2019, shows that the registration requirement is currently 15,439, and the party has 15,486 members, so the party has a margin of 47.
Last month, following a voter registration purge, the party only had a margin of 7.
The party did not meet the alternate 1% vote test because its only two statewide candidates were for Governor and U.S. Senate. It got .91% for Governor and .96% for U.S. Senate. Both of those races were considered too close to call, although Democrats ending up winning both of them, and gaining a U.S. Senate seat. The Libertarian Party would easily have met the 2018 vote test if it had bothered to run candidates for the lesser statewide offices, such as Treasurer.
