In addition, birds should get 1/16th of a vote, rabbits 1/20th and snail darters 1/32nd of a vote. Subject to Senate approval, of course.
What percent of a vote would dead people get under your scheme? Whoops... Dims already make sure they vote early, often, and Democrat.
Remember, the underlying premise behind giving the vote to people who do not "deserve" to vote (like immature, irresponsible children)is that they can easily be manipulated into voting Democrat.
In the case of dead people, they can 100% be manipulated into voting Democrat, and since they were at one time "adults", they should get 100% as much of the vote as an undead" person would. It's only fair.
