it would take a lot of people to change the "culture" overnight. likely a prohibitively large number, as you said. but it doesn't take so many newcomers to significantly change political outcomes. even in red states, republican mayors are pretty rare. in practice, this means that the mayoral race is almost always determined by an n-way democratic primary. it's hard to overstate how chaotic this can be. for example, the current mayor of baltimore won the 2020 primary (effectively the general election) with <30% of the vote, with the runner up trailing by only 2%. this was an election where ~25% of the population cast a vote. it would have taken <4000 votes to completely change that outcome.
