The Conventional Wisdom is that those who aggressively cleanse voter rolls want to disenfranchise voters. There are dark hints that this is a form of crypto-racism. I'd like to suggest that election fraud is an indirect form of voter disenfranchisement.
Suppose you honestly cast your vote for candidate X, but a political hack drives a spike through a stack of ballots for candidate Y. This invalidates all votes for anyone who is not candidate Y. This disenfranchises all of those voters in the sense of negating their votes (if not in the sense of turning them away from the polls). This is an obvious direct form of disenfranchisement of honest voters by a dishonest party.
Or suppose the names of dead people are put onto the voter rolls. These dishonest ballots dilute the force of honest voters. It doesn't completely negate the honest voters' votes, but it partially disenfranchizes them.
It doesn't matter if you are Republican, or Democrat, or Green, or anything, election fraud steals from everyone.
