I think you’re confusing the responsibilities of states and local municipalities. It may surprise you to learn that Jackson is actually led by a quite liberal mayor: https://www.jacksonms.gov/departments/office-of-the-mayor/
The mayor has been begging* for funds from the state for a long time now to fix the problem though. That being said, I'm sure there is lots of local and state mismanagement that would go into causing such an embarrassment. * https://www.wlbt.com/2022/02/17/jackson-faces-uphill-battle-...
Maybe they are worried about the political implications of rising property taxes or water bills?
Seems like a HUGE failure by an inept local government.
