Nope, not with the demographic shift this country has experienced.
I agree that we have had a demographic shift but I think the bigger issue is the cultural shift. There are Christian / conservatives in all of the different demographic groups (white, black, Asian, middle eastern, etc.) but as long as we (conservatives) continue to hand our children over to the public schools (liberals) to be educated then we have already decided to surrender.
The numbers I have seen, seam to show that conservatives tend to have more children then liberals and yet we hand them over to the liberals to “educate” them (around 90% of Christian/conservative kids attend public school)
