So I’m assuming he’s referring to violent crime rate rankings, because as Alex Denethorn’s answer points out, “most dangerous” can change depending on what list you use. If you think that violent crime rates is the measure of this, then the top ten do all have Democratic mayors.
But you know what else? So do nine of the top ten largest cities in America, and twenty-five of the top thirty largest cities in America, and four of the five safest large cities in America.
Being controlled by Democrats has nothing to do with the city’s crime rates, it has to do with them being cities.
In general, cities vote for Democrats and rural areas vote for Republicans.
Most of the cities with the highest crime rates are going to elect Democrats because most cities in general elect Democrats. The cities with the lowest crime rates also elect Democrats. Obviously cities are going to have more crime than rural communities because they have more people. If 1% of people are criminals then a town of 10,000 will have 100 criminals but a city of 1,000,000 will have as many criminals as that small town’s population. But you could just as easily say that the most dangerous rural communities in America are run by Republicans, because most rural communities are run by Republicans. Maybe Trump would understand this if he didn’t pay people to take his tests in school but correlation does not equal causation.
