Trump 52%
Clinton 46%
Others 2%
Louisiana went for Clinton 52-40 in 1996. What has changed since then is that the Cajun Catholics have swung to the GOP; prior to that, they had become the key swing voter group at the Presidential level and the folks that kept local politics in Louisiana Democratic.
I predict something of a comeback for Hillary amongst the Cajun Catholics. Not enough to win, but enough to improve.
I don't really see a reason for a comeback. Much of cajun country is rural, not very high income or education levels, and pretty socially conservative.
