The re-election of Barack Obama triggered a flood of truly ugly, racist tweets.
A group of geography academics calling themselves the "Floating Sheep" scoured Twitter for the racist tweets and tracked them down by state of origin. Voila.
Yellow states had relatively low levels of racist tweets. Green states were found to be the source of high levels of racist tweets.
"Alabama and Mississippi have the highest LQ measures: They have scores
of 8.1 and 7.4, respectively. And the states surrounding these two core
states -- Georgia, Louisiana, and Tennessee -- also have very high LQ
scores and form a fairly distinctive cluster in the southeast."
The article, from Atlantic, gives examples of some of these tweets. If you feel the need, you can read them there.
