The old geezer DIMs probably forgot that they voted already because they did not impregnate the chads this time, so they went back to vote again.You may be on to something here. I'm not a DIM but I AM a geezer. And in my lifetime I've impregnated so many chads there's no way I can remember all of 'em.
Why, just the other day I was impregnating a chad and she said to me, "Hey, I remember you! Didn't you impregnate me once before in the 1968 election?"
Had to admit I did. Very embarrasing! But also comforting that she remembered.
