Your “not rocket science” observation seems factually correct but too simplistic. What we should want to do is to allow people who are eligible to vote and to do so without intimidation. For those not eligible, find out why before sending them away. For example, all states should have same day voter registration. Today, states with Republican legislatures are removing that feature. Studies show that about 9% of people who try to vote in those states were removed from the rolls. Sometimes in error and other times because the state assigns a window of time in which you must vote to remain on the rolls. That’s wrong because no one ever said that if you don’t buy a gun in a certain amount of time, you forfeit your second amendment rights. The right to vote should be a lifelong right. Anyway, the goal of a participatory democracy is get as many people to vote as possible. Imagine the intimidation if a poll worker begins to challenge every eligible voter? Even fewer people will vote. We don’t want to make the voting booth like the DMV. I don’t think you’re wrong just a bit too unrealistic.
