Now, what can we conclude from all this information? Well, firstly we can conclude that NP's poll is the least scientific and the least reliable. We can also conclude that Americans have been increasingly supporting SSM ACROSS THE BOARD. All demographics have shown increasing support... including Republicans and older adults. For example, according to the Pew data, only 21% of older adults supported SSM in 2001; in 2013, 36% supported it. In 2001, Catholics were at 38% and Protestants were at 40%; in 2013, Catholics were at 55%, Protestants 54%. Even Evangelical Protestant support went from 13% to 23% between 2001 and 2013.
The CBS poll shows that Republican support for SSM has changed from 13% to 37% just since 2012.
Ultimately, the conclusion is this. More and more Americans are supporting SSM across all demographics. Of course, there will always be a few opponents who will ignore information and research and stick to their biases, but as we can see, those people are becoming fewer and fewer.
