Obviously, we all know what's actually responsible for Mary Landrieu's Senate loss - racism - but what we haven't discussed is exactly how terribly Mary Landrieu performed in her runoff against Bill Cassidy. We should, because the 9th Senate seat pickup for Republicans wasn't just a subtle, narrow win on the heels of a much larger national trend. It was the kind of delicious, total walloping that comes around perhaps only once a cycle, if that. The only close thing in recent memory, that I can think of, was that time I agreed to do a shot of blue alcohol every time Mitt Romney lost a swing state in 2012.
Anyway, here are some of the gorier details.
— Cassidy won 49 of Louisiana's 64 parishes. Six years ago, when Landrieu defeated Republican John Kennedy without a runoff, the Democratic senator carried 38 parishes.
