Excuse me? Please elaborate.
Church teachings are pretty clear in terms of divorce, and its opposition to the death penalty had been stated in no uncertain terms. Yet divorce is freely available and is subsidized by the federal government, and Catholic politicians need not fear when they support those laws. Opposition to capital punishment would be the kiss of death for many a politician's career, and likewise the Church doesn not sanction politicians who support that. It all depends on the popularity of the sin.
