Why did that county in northwestern Louisiana voe for the dem?
Just an accident of low turnout.
Is it just me, or was that a really impressive performance for the Dem candidate considering that he wasn't even trying to win?
It really is, but a big reason was the mayoral race in New Orleans really helped drive out turnout for him.
That's basically the entire reason. Notice that Edwards lost Caddo and EBR, which generally go D.
Am I Wrong being surprised that neither Shreveport nor East Baton Rouge Parish went democratic? Especially the latter?
Nope, it's definitely a surprise.
