Here is a current tally for voter registration in Louisiana, for all parties, qualified and unqualified alike. All the qualified parties increased their share of the registration since November 2016, except for the Democratic Party.
The June 30 percentages for the qualified parties are: Democratic 44.07%; Republican 30.12%; Independent Party 1.94%; Libertarian .48%; Green .09%; Reform .04%; unqualified parties and independents 23.22%.
The percentages just before the November 2016 election were: Democratic 44.49%; Republican 29.73%; Independent Party 1.87%; Libertarian .47%; Green .08%; Reform .04%; unqualified parties and independents 23.28%. Back then, the Independent Party wasn’t ballot-qualified, but it became ballot-qualified early in 2017. The law requires 1,000 registrants plus payment of a fee of $1,000, and no one paid the fee until early in 2017.
The largest unqualified party continues to be the Conservative Party, which had 844 registrants in November 2016 and which now has 839. Thanks to Randall Hayes for the new data.
