Re Correlation is still not causation.
The reality is that what one truly believes is the cause behind how one votes, presuming he is informed and understands. Otherwise religion is meaningless, and being Catholic would have no bearing on their opposition to abortion. But what we do see is an overall consistent substantial correspondence between faith groups and predominate moral and political views, indicative of commitment to said faith, and or discernment.
Thus Hindu Asian-Americans were at 9%/72% Republican/Democrat, while Asian-American evangelicals were at 56%/28% and Asian-American Catholics were at 42%/41%.
The fact that there are anomalies to how faith is manifest does not negate faith as being the cause, but reveals that in such cases other factors overcome what one professes, or testifies to lack of discernment, and manifests what such really believes. And the less articulate or demanding a faith tradition is, is also overall reflected.
Obviously if all Evangelicals and Catholics really believed that abortion and homosexuality as well as the victim-entitlement mentality disallowed voting for candidates that supported such when there was an alternative, then they would not be voting for the liberal.
Thus while there are many factors involved in determining how a person will vote, his vote manifests what he really believes and understands and is the real cause behind his informed vote, as well as his other actions.
And what the stats indicate is that evangelicals as a whole are more committed, in opposition to culture, and or have better understanding, or find it easier to support candidates who best represent the traditional morality which his faith requires.
Or it could be the racial/socio-economic, cultural composition is quite different to begin with.
I agree. All Christians need to do a better job of instructing their congregants on the importance of all their teachings.
And all Christians need to do a better job of helping others come to Christ.
