As the Christian faith grows in the southern nations, they will be the ones to send the missionaries to the USA and the west.
I could get any polled put in favor for my own agenda based on where I poll.
For instance if I want to make it look like we are not a Christian nation then I would poll in certain Dem areas in the north east.
If I wanted to make it appear that most want homosexual sham marriage then I would poll in that same area in Boston, Chicago, NY City etc. I f I wanted to make it appear that the country is opposed then I will poll in more rural areas, in the south and Midwest.
