How did the bourbon democrats acquire and keep power in Louisiana during late 19th century

The election of 1892 and subsequent efforts to fundamentally rewrite state electoral law in 1896 remained the only remaining obstacles for Louisiana to have true one-party rule in both name and in deed. Not until the Farmer’s Union movement was suppressed through cooperation between both Bourbon and Reformer Democrats could true disfranchisement take place. The potential for bi-racial cooperation in the Farmer’s Union movement scared Bourbons into realizing that they were playing with fire by keeping black labor on the books. With the lottery money now gone, they also had little hope but to go along with the Reformer Democrats program of disfranchisement.  The disfranchisers overreached in 1896, however, with a law that would have taken the ballot from most of Louisiana’s poorer whites. The widespread rejection and unrest cause by such proposals led directly to modifications such as the infamous “grandfather cause” of the 1898 State Constitution, an amendment that provided political rights for poor, illiterate whites but not their black counterparts. With its ratification, a new era dawned in Louisiana politics.
