Baltimore would be a perfect test bed for this. A third black female mayor failed miserably. A local news anchor was fired for merely asking if that was the problem. It’s been many decades since any Republican was in office. The city is ripe for a strong fiscal conservative who is willing to burn down the current government.
Alas, I can’t think of one such person in the city
The last GOP Mayor of Baltimore was Ted McKeldin from 1963-67 (he had also served previously as MD Governor and before that, previous as Balto Mayor in the ‘40s). Unfortunately, McKeldin was NOT a Conservative and at the time he was Mayor, it was still a White majority city.
