Our friends at The Texas Tribune have provided a simple explanation of recent changes to the way the Republican and Democratic parties conduct their precinct elections. In the past, precinct conventions have been held on primary election night immediately after the polls close. The meetings were an opportunity for local party affiliates to elect delegates to their party's county or senatorial district conventions and discuss proposed resolutions to the party's official platform. This year, the Democratic party and some precincts within the Republican party are opting not to conduct precinct conventions tonight. They will instead assemble local delegates prior to the county or senatorial district conventions on March 22. Read more details here, and check with your local party to find out how to participate in your party's electoral process.
