Numbers would be interesting: 
What percentage of nominal/self-identifying "Catholics" support the death penalty?

How does this break down by mass attendance, frequency of confession, generation/age, mode of reception of Communion, agreement with other Church teachings, preferred form of the Mass, liturgical preferences in the Ordinary Form, frequency of Eucharistic adoration or other devotions, familiarity with the Catechism, etc?

The linked article is very intelligent, but it's too bad that nobody at the newspapers or other organizations that typically commission polls are asking just what kind of "Catholics" voted against Church teachings in Nebraska.
