From Texas Standard:
As Texans gear up for the 2020 elections, some hopeful candidates are struggling to get on the ballot. As a result, the Libertarian and Green Parties and others have sued the Texas secretary of state's office, alleging election laws in Texas discriminate against third-party and independent candidates.
Mark Jones is a political science fellow at Rice University’s Baker Institute, and says candidates who want to get on the ballot for the governor’s race, for example, but who haven’t won enough votes in past elections, have to get signatures from the public.
