By the logic of one Democrat, it means always endorsing the black candidate in an election where they're running against a white person:
Chicago mayoral candidate Carol Moseley Braun on Wednesday reminded former President Bill Clinton that the black community stayed loyal to him during the Monica Lewinsky scandal as she called his campaign appearance for Rahm Emanuel a “betrayal” of the city’s African-Americans and Latinos. “The African-American community if you remember when he was having Monica Lewinsky problems stuck by him,” Braun said told NBCChicago at an event on Chicago’s north side.
“Then to go and not endorse any of the minority candidates, or just to stay out of it, that would have been the best,” she added. “The minority community stayed with Bill Clinton when Monica Lewinsky almost took his job.”
In a statement issued earlier in the day, Braun said. “For him to come on the day following Dr. Martin Luther King’s birthday to insert himself in the middle of a mayoral race, when the majority of the population and mayoral candidates are African-American and Latino, is a betrayal of the people who were most loyal to him. It’s a mistake.”
What a distasteful worldview. The best way to be loyal to black people in Chicago is to endorse the person who'll lead their cit most effectively, regarless of his or her race.
