Overall, older voters have tended to be more Republican than younger voters in recent decades, but this is not true for Black voters. While 7% of Black voters 50 and older currently identify as or lean Republican, 17% of Black voters under 50 are aligned with the Republican Party. This is not new, as younger Black voters have tended to be more Republican than older Black voters over the last 25 years.
