As someone who's lived in both Rhode Island and Illinois, those two states are so dead on as the ones with the least pride.

Rhody has a huge inferiority complex due to being sandwiched between two wealthier states with more resources, both of which are easily reached from anywhere due to RI's tiny size.

Illinois is completely dominated by the Chicago area, which has its own strong identity, and Chicago-area people look down their noses at the rest of the heavily rural state. Then people elsewhere in Illinois bash the state for being dominated by Chicago.
