On December 10, the Libertarian Party national committee met in New Orleans and decided that the party’s 2020 presidential convention will be in Austin, Texas, over Memorial Day weekend. As far as is known, no other political party, major or minor, has yet chosen a location for its 2020 presidential convention.
In 2016, the party held its presidential convention in Orlando, Florida, May 26-30. Thanks to Independent Political Report for the news about the 2020 convention.
