| With the Louisiana redistricting map one of the first to emerge intact from the sausage-making process, it's time to crunch the numbers and see just what kind of districts we wound up with. (Notice that I'm not saying the map is a done deal... the Obama DOJ might still weigh in and shake things up, as they could conceivably push for a second African-American plurality district under the VRA.) Our resident data guru, jeffmd, has sliced and diced the shapefiles on the state House's website, overlaid that onto the VTDs available from the Census Bureau, matched the VTDs to 2008 and 2010 election results available from the Louisiana SoS website, and voila:
The full precinct-by-precinct dataset, courtesy of Google Docs, is available here.
If you aren't familiar with the contours of the new map, you can take a look here. In a nutshell, the 1st remains the New Orleans suburbs, the 2nd remains New Orleans proper (although now it reaches into Baton Rouge's African-American neighborhoods as well), the 4th is still centered on Shreveport, the 5th is still Monroe and Alexandria, and the 6th is still centered on Baton Rouge (even if its core is now missing). The big difference is the 3rd, which now mostly occupies what used to be the 7th, across Lake Charles and Lafayette; the old 3rd, in Cajun country south of New Orleans, has been parceled out to the 1st, new 3rd/former 7th, and also the 6th and 2nd.
As you can see, the redistricting result is very, very likely to result in a 5-1 map. The friendliest district for Dems, after the 2nd, is now the Shreveport-based 4th, but even it didn't even see Barack Obama hit 40%. That's not much different from the current setup (where he did hit 40%); the old 6th was the friendliest for Dems, but barely more so (with 41% for Obama).
Greg Giroux has some other interesting tidbits available on how the 3rd district (which is now poised to become a battleground between incumbent GOPers Charles Boustany and Jeff Landry) got neatly dismantled: Boustany represents 575K of the 3rd's residents, while Landry represents only 180K of them, a nearly 3:1 advantage for Boustany. Of the old 3rd, 29% of it wound up in LA-01, 28% in new LA-03, 24% in LA-06, and 18% in LA-02. (The Daily Kingfish has picked up on this, and speculates that Landry might be better off challenging Steve Scalise in the 1st instead.)
