Plaquemines Parish extends along the Mississippi River delta into the Gulf, and its economy — long anchored by oil, gas, and fishing — correlates with voting margins that have trended decisively Republican over recent cycles, reaching R+38 in 2024.
The unraveling was not abrupt. The Democratic margin in Plaquemines Parish peaked at ninety-six points in 1932; it narrowed steadily over the late twentieth century. The 2000 election delivered the county to the Republican party for the first time in many years, by a margin of seventeen points. By 2024, the margin had settled into deep Republican territory.
