Let me correct that....
Both Catholics and Protestants have large groups who claim to be members but have not entered a church in years. I suspect very few of those who attend either church (not including blacks or Mexicans) supported this guy.
My Evangelical father-in-law who is in Church twice a week probably voted for Obama. His parents were hit hard during the depression and has blamed Repubs because of that.
Church going Christians voting for dems is a reality all in the name of social justice (Their excuse).
