A significant number of Louisianans leaving the GOP because of its presumed association with violent activity around the U.S. Capitol? Absolutely fake news.
Even just a surface knowledge of Louisiana politics and electoral behavior in general should brought skepticism to a headline screamed by the Louisiana Radio Network: “State GOP membership sees trend-breaking dip post January 6th US Capitol attack.” Its content argued, apparently reviewing first quarter 2021 numbers, that Republicans shed registrants disproportionately, with most of that occurring in January, hence the association with the episode of unrest (see the stylebook). It noted drops of that magnitude didn’t happen in 2017 (slight gain) and 2013 (slight loss), true for both the first month and first quarter.
However, insofar as voting partisanship has little meaning in Louisiana state politics. With the blanket primary system in place, little reward or punishment accrues to registering a certain way. One could argue, as one of my colleagues at Louisiana State University (who probably didn’t look at the data himself) that changing a registration could serve as a symbolic penalty on the party, but when the symbol means so little substantively relative to the act of voting in the first place, that seems unlikely as a response.
