I compared JBE's overperformance from 2016 in each parish compared to that of the state as a whole (which was 22.24%). That is, it's a comparison of what he actually got vs. what he "should" have gotten had there been a uniform swing. The results were wild.

So Edwards did worse, relatively speaking, than Clinton in much of rural LA. That is... not what I was expecting. At all.
I think it's a sign that there are some rural white voters who normally vote Republican but still consider the Democrats, but not many, so narrowing the margins in rural areas substantially is tough even for a candidate with on paper a lot of appeal to those voters, but there are a lot more normally-Republican suburban voters who are starting to consider the Democrats as an option.
