I recommend Sacramento, California for relocation. There's the river delta, similar summer climate, (heck, they even have a Jazz Festival)good housing and jobs (compared to anything they'll ever have in N.O.)
An organized contingent of NO refugees could absolutely thrive in that town.
Being out of New Orleans has to improve their chances.
Importing more Democrat voters to CA?
No, let them be taken on by red states where the group think there may rub off on them and they may be able to turn their lives around and make progress instead of stagnating in a welfare state, where Democrats encourage them to consider themselves helpless victims, reliable voters that will sustain them in power.
Similar summer climate?!? You've been stuck in Sacto too long, honey. Plus I don't know where someone from Louisiana is gonna come up with over a quarter million dollars for a 50 year old 1200 sq.ft shack on a postage stamp yard in Del Paso Heights or Ghettoview...uhhh...I mean Meadowview. I left Sacramento 2 years ago, and it is still the best thing I've ever done to improve every aspect of life for me and my family. Besides, Sacto doesn't need any more Democrat voters.
