The Louisiana problem is precisely the same as Alaska's.  The Koch brothers in particular got an incompetent governor elected and with redistricting, a similarly inept legislative majority. The Kochs even got judges elected to appeal courts. 

The did it the same way:  Hollering about "abortion," "homosexuals,"  "regulations," and "taxes," red meat issues that appealed to the lowest information voters.  

They even permanently exported a great deal of the state's black population post-Katrina, most of them to the Houston area.

They got what they paid for: Tax givebacks and progressively more insufficient oversight of industry and business.

Piyush Jindal tried to paper those problems over by selling state assets. Everything went on the block: Schools, bridges, prisons,roads, even the state capitol buildings.

The only reason they have a decent, competent governor now, is because Vitter couldn't stop  patronizing prostitutes and some of the fundamentalist right had a problem with that.
