As we approach another presidential election, the subject of voter screening is once again emerging as a purely partisan fight. Republicans are supporting laws that require a person to identify himself before casting a ballot; Democrats oppose such laws. Democrats accuse the Repubs. of trying to “disenfranchise” the downtrodden proletariat by making them show ID when they vote. The Republicans claim, with some basis, that they are only trying to “disenfranchise” illegal aliens, cartoon characters, and dead people.
