Well if we're going to talk about the inherent value of choosing a "lesser evil" (divorced from the context of Fr. Tauok) it does have some place in moral theology. St. Alphonsus (per McHugh and Callan) taught that a preplexed conscience which cannot delay a decision must select the lesser of two evils. That goes for individual, private morality. In the public realm, the state is certainly allowed to tolerate lesser evils in the pursuit of staving off a greater one (this of course is a different situation, only bringing it up under the heading of lesser evils in general and their place in Catholic moral theology). So it isn't right to say that it has no place at all, even if it has no place in the current context of there being a moral obligation to vote.
