Final answer:
Individuals who are members of labor unions in Michigan and identify as African American are historically more inclined to vote for Democrat candidates, as the party has been supportive of pro-labor legislation and civil rights.
Step-by-step explanation:
Given the historical context and the demographic details provided, individuals who are members of a labor union in Michigan and identify as African American would tend to vote for political candidates who are Democrat. This trend has historical roots as the Democratic Party has historically included diverse socio-economic backgrounds and has been associated with supporting pro-labor legislation, civil rights, and public welfare programs. Northern workers' loyalty to the Democrats was strengthened by initiatives such as the Wagner Act, and African American support shifted due to the New Deal providing federal jobs with equal wages. Additionally, unions have often shown strong support for Democratic candidates who advocate for laws that protect worker rights such as work conditions, overtime, and parental leave.
