Honestly, lots of people don’t vote, because they either can’t (people who served time in states where they don’t reinstate voting rights) or because they feel as if it’s not going to do them any good, it won’t change anything. Looking around at the current situation we’re in, can you say that they are wrong? Especially with the gerrymandered districts, among other things?
I go vote, but even I’m not sure it’s doing much good, honestly. All my state and federal districts are democratic and I’m in fact represented by African Americans all the way down (I think even in my county now, which was previously an all white county board).
