Roybal Caballero is correct when she says "that our Catholic faith teaches that women and men have the right to make their own [moral] decisions ... based on the dictates of their own consciences." Indeed, everyone has a moral obligation to act according the dictates of an informed conscience.

Her statement does not contradict what the bishop says: "It is not morally permissible for a Catholic to support abortion or doctor-assisted suicide".

The issue is more subtle: When should a Catholic oppose legislation regulating "immoral" behavior? Catholics do not seek legislation forbidding adultery or divorce. I see no reason, in principle, to oppose legislation regulating prostitution, gay marriage or euthanasia. Abortion is arguably different in that it involves more than willing adults. And even then, indifference about the consequences of criminalising legislation could itself be immoral.
