Blue cities in red states are routinely underfunded and sorely lacking in resources. One need only look at history of the Jackson Mississippi water crisis and how many times the Republican state legislature has stripped the City of funding for new water treatment facilities claiming that the Democratic city government is "corrupt", and cannot be trusted with the money. Funds are redirected to the white suburbs.
This is the same thing that happened in the Flint Water crisis. The Republican state government declared the Flint government "corrupt" and forced them to use the tainted water, because the corrupt city government could not be trusted to make sound decisions.
Such degradation of city services, crime rates, and education scores doesn't happen in large cities in blue states, because blue states ensure reasonable levels of funding to their cities. Heavily gerrymandered red states retain control of schools, hospitals, and infrastructure funding.
Corruption at the municipal level is endemic - regardless of which party controls the cities. That's because city officials are the easiest to bribe, being the lowest paid. Red states only claim corruption if the council and mayor's office are in the bands of minorities. As long as the city is controlled by Republicans, no corruption will be noticed or commented on. The moment minorities take over, city hall is rife with it and money will be never be given to the cities.
