Democrats complain about gerrymandering as if it's something only Republicans do but, as we've seen in states like New York and Oregon, they implement the same district-map-drawing schemes when they have the majority. Gerrymandering has occurred from both sides since the nation's founding, and Louisiana has the same right to draw maps the way they want as New York and Oregon do.
Democrats have certainly been the party calling for an end to the GOP's unethical, racially-based gerrymandering for at least a decade. That being said, without a clear and likely national resolution to the problem soon, the Democrats should continue drawing up districts to benefit themselves as much as possible or they'll risk losing the legislature in this year's midterms.
Both Democrats and Republicans gerrymander massively, making American democracy far from fair. Election laws should change.
