Look, LA is not AR or TN. Democrats can still win there. Even Landrieu got 44% despite her terrible campaign.
Low excitement about the election and the runoff system probably helps republicans.
If anything, that helps the Democratic candidate. Southern Blacks turn out at a higher rate than AAs in other parts of the country, whether it's a runoff election or not.
I don't really see what was so bad about Landrieu's campaign. What else could she have done?
Not playing the race card might have helped. Oh, and maybe not calling your constituents racist and sexist might have helped as well. And not hiding from Obama too. I could go on and on. Given that campaign, she shouldn't have gotten 40%, much less 44%. The 2014 (and 2012) results were a warning sign for the LA GOP.
Sometimes, I wonder if you live in the same South as I do, especially since you probably live closer to me than any other Atlas user...as if doing/not doing any/all of those things would have made a difference. Southerners are notorious for making up grievances out of thin air - especially if they're racial in nature - and so all she did was prevent the cretins of Louisiana from having to lie about why they weren't going to vote for her.
