It's no secret that certain states hate other states. The east coast doesn't like the west coast, and the midwest hates both of them. And nobody likes New Jersey. This graph details which states hate which other states the most, with some expected results, and some surprising twists.

Unsurprisingly California hates Texas, showing a rivalry between the two biggest mainland states, while Texas turns its ire towards neighbor Oklahoma. South and North states don't like each other such as the Dakotas, and many south eastern states despise Florida, including the state itself. Unsurprisingly New Jersey is unpopular with every state that has to deal with it, and the Mass-holes aren't well liked around New England either. We all have states that we really don't like for one reason or another. Perhaps it's our common hatred of each other, or New Jersey, that keeps us together, and makes us one unified nation.
