After all every murder infested (rat infested too for that matter) are within a state which also has a government politically controlled by one or the other party.
Guess which state has the highest murder rate (at least in 2017 which is the last year with available stats)? Nope not CA or NY and not AL (but 'Bamas not far behind). LA (the state not the city)...Today LA now has one statewide office held by a rather right of center Democrat, but in 2017 it was top to bottom ruby red including the legislature! OOPS
Most of the top 11 states with the highest murder rates are red as a tomato.
