States that vote Republican, but vote Democrat for some local elections are a few states, Louisiana being one of them. We have more registered Democrats than Republicans, but have a high amount of Independent voters. We typically have low turnouts by Democrats in our urban cities of New Orleans, Baton Rouge, and Shreveport on top of our Independent voters are usually conservative leaning Republicans masquerading as if they have no preference (LIES)
We've had a Democrat Senator (Mary Landrieu), but she got booted in '14 because we didn't show up for the runoff election. To win in LA for state elections, you have to win with 50% + of the vote or the top two go into a runoff, where the special election is like a month later. We got lucky to get a Democrat Governor last year (John Bel Edwards), mostly due to the GOP producing a failure as their champion (David Vitter). Vitter's scandals were so bad, they had Republicans and Indys voting for JBE. Democrats best chance to get a seat is to only allow one to run and let the GOP take votes from one another. We just need voters to turnout.
