The political landscape and the hot button issues change around them and not many can keep up.
My 90 year old aunt had registered in Florida back in the days when it was a one party state and if you didn’t vote in the Democrat primary you had no say at all in who the candidate was for the general.
Come to find out my aunt is still registered Democrat even though she thinks J.E.B. can walk on water and has voted straight Republican forever, like her ancestors.
It is too much for her to do to just get the garbage can out to the sidewalk on pick up day, let alone reregister in her real party.
I know what you mean. At least she’s spry enough to know the right folks to vote for. Good for her.
