Changing election day to a Sunday might help, but without meaningful choices in the voting booth, the majority of voters will still find better things to do. Exactly the same thing happened during alcohol prohibition when every high school had its own bootlegger. Entire schools were closed because of student drunkenness. Finally the mothers of America realized the damage the alcohol prohibition laws were doing their children and demanded an end to the Volstead Act. After repeal, bootleggers disappeared from the schoolyards of the United States and alcohol consumption among children dropped tremendously.
History repeats itself as the drug black market comes to maturity.
Because of our insane drug laws it is easier for a kid to get a shot of heroin than to buy a beer. The reason is simple. Licensed liquor stores check ID cards, while black market drug dealers sell to all comers with cash in hand, no ID required. Repeal got rid of the bootleggers in the schools, and ending drug prohibition will get rid schoolyard drug dealers. Additionally, Christians boast that they are able to differentiate between the sinner and the sin.
