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.
Plus some folks who have Christian faith, concerned that they do not want to be attacked, will sadly do some “little white lies” to poll takers.
I would examine the results of the polls that occur in November of even-numbered years ...
