Reps. Mike Lang (R-Granbury) and Matt Rinaldi (R-Irving) filed separate bills (House Bill 1061 and House Bill 1072) that would require partisan voter registration and limit voters to participating in the primaries and/or conventions of their indicated party. Voters choosing not to indicate a party preference on their registrations would be listed as “independents” and barred from participating in any party’s nominating process. Voters may change their affiliation status, but must do so before the 31st day before a primary to be eligible to vote in that primary.

As far as we can tell, Texas has not required partisan voter registration since the abolition of the poll tax and creation of statewide voter registration in 1966.

In a press release, Lang said his intent was to prevent voters from other parties from interfering with a party’s nominating process. “I do not want a Democrat voting in a Republican primary just as much as I don’t want a Republican voting in a Democrat primary in order to sway the election and degrade the integrity of the race,” Lang said. He cited an email sent by the Hood Co. Democratic Party encouraging Democrats to vote in the Republican primary election “to get a more liberal candidate” elected. Lang won the 2016 Republican primary, 54%-46%, over Granbury banker Kevin Downing.

Despite record primary turnout in 2016, Texas still ranked 29th out of 39 states holding presidential primaries, including a state that held just one party’s primary. Four states ranked below Texas held partially closed or closed primaries: Connecticut, Delaware, Kentucky and New York. Three other states – California, Nebraska and New Jersey – held primaries after both presidential nominating contests were settled. Texas ranked last among states holding an open or partially open primary.

Status of Voter Participation in Partisan Nominating Processes

We have classified each state’s rules for partisan primary/convention participation based on the ability of voters to choose in which party’s nominating process they wish to participate.

Partisan registration is required in 31 states, but only nine states fully restrict participation in a party’s nominating process to those voters already registered with the party.

Closing the primary to registered partisans is listed as one of several “election integrity” priorities by Texans for Fiscal Responsibility/Empower Texans.
