The unionized, African-American population from Michigan is likely to vote Democrat.

The three characteristics given in the question can serve as hints indicating the person's voting tendencies.

Member of a labor union. Labor unions are organizations which strive to defend workers against what they perceive as the harmful effects of market mechanisms (too low wages, too many working hours, unsafe working conditions ...). Unions are asking for the state to intervene and protect the workers by creating laws, for example. On the political spectrum, the Democratic Party is the most likely to encourage a bigger role of the state in affairs such as the market. Therefore, workers who are unionized are likely to vote Democrat. Living in Michigan. In terms of geography, U. S. states in the upper half of the country are more likely to vote Democrat. Yet historically, Michigan has been a "purple state." This means that the voting majority is rarely categorically Republican (whose associated color is red) or categorically Democratic (blue). For example, Michigan's inhabitants tend to support Republicans as presidents and senators, but elect Democrats to local positions. This is why the other hints provided by the question are necessary. Identifying as African-American. When looking as voter demographics over history, African-Americans have tended to vote primarily Democrat since the 1950s. There are many reasons for this tendency, including the fact that the major bills and laws in favor of African-Americans (like the Civil Rights Act of 1964) were passed by Democratic governments.

It is important to note that humanities are rarely, not to say never, an exact science. There are such things as conservative trade unions and Republican African-Americans. This answer only tackles the question of who an individual is likely to vote for according to his/her identities and characteristics.
