Is it actually poorer than New Mexico, where I live?
Here is a listing of personal income by US State. Although it only goes to 2014. New Mexico is ranked 43rd by median income, 46th by per capita income. Mississippi is ranked 50th (poorest) in both categories.
Too bad Gov. Bryant is not willing to die in support of an improved standard of living for his state's residents. But anti-LGBT hatred resonates with his undereducated voter base (Mississippi is also last in the US by most measurements of education and school expenditures & performance), and that tactic will get him reelected.
"Party Before People" is the Republican Party motto, sorta like the totalitarian Communist Party. And getting reelected to stay in power to enrich themselves and their donors is the only goal they seek. Gov. Bryant is the personification of their self-serving philosophy.
A representative democracy only works when the elected representatives promote & protect the interests of their constituents, not their own personal interests. If our US form of democracy fails, self-serving elected office holders with a lack of commitment to the interests & welfare of all citizens will be a major cause.https://en.wikipedia.org/wiki/List_of_U.S._states_by_income
