Why is Louisiana never competetive?

[DINGO Joe]

It's a little surprising that Louisiana has become almost as polarized as Mississippi, considering that Louisiana has a place as cosmopolitan as NOLA.  If the New Orleans city limits were removed from the state, would Louisiana whites even be more right-wing than Mississippi whites?

Well, Mississippi is more black 37.8 to 32.7 than Louisiana, so not really.  Without doing any math, I'd guess Louisiana without NOLA would be less than 30% black.  North Louisiana is basically West Mississippi though.
