Some of the most dangerous big cities are: St. Louis, Detroit, Baltimore, Oakland, Chicago, Memphis, Atlanta, Birmingham, Newark, Buffalo and Philadelphia. The most common characteristic of these cities is that for decades, all of them have been run by liberal Democrats. Some cities — such as Detroit, Buffalo, Newark and Philadelphia — haven't elected a Republican mayor for more than a half-century. On top of this, in many of these cities, blacks are mayors, often they dominate city councils, and they are chiefs of police and superintendents of schools.

In 1965, there were no blacks in the U.S. Senate, nor were there any black governors. And only six members of the House of Representatives were black. As of 2019, there is far greater representation in some areas — 52 House members are black. Nine black Americans have served in the Senate, including Edward W. Brooke of Massachusetts, Carol Moseley Braun and Barack Obama of Illinois, Tim Scott of South Carolina, Cory Booker of New Jersey, and Kamala Harris of California.
