Jim Crow Finn duffey
Jim crow laws affected black people politicaly in many different ways one of these ways is a grandfather voting clause. This means that if your grandfather could not vote then you could not vote. This really affected the first generation of people who weren't enslaved because there was no chance that their grandparents could vote. Another way that they affected is in unfair court cases in which the defendant may be innocent but just because they are black they are prosecuted.
