"The proportion of the [American] population that can be classified as Christian has declined from 86% in 1990 to 77% in 2001." ARIS Study, 2001. (It reached 76.0% in 2008.)

The way I see it, if you are going to determine how many of this 76% (while searching I found differing results, ranging from 67% to 81%, so settled on this figure for balance) are "real" Christians then you are going to need to have looked into the heart of every one of the 76%. God alone, when all is said and done, decides who are "real" Christians and who are not.
"Can America still be called a Christian nation? It is certainly a more religiously pluralistic and diverse society than it was during the 18th, 19th, and early 20th centuries. There are increasing numbers of non-Christians immigrating to this country, and there has been a rapid rise in adherents to Islam among our population. There are millions of Muslims, Jews, Buddhists, Shintoists, Unitarians, Hindus, Wiccans, Naturists, Agnostics, and Atheists, but Christians comprise roughly 84%[*] of the population. Our constitutional legal system is still based on the Jewish/Christian Bible, not the Koran or other holy book. We still observe Sunday, the Christian Sabbath, as an official holiday. Easter and Christmas still have a special place in the holiday lexicon. The Ten Commandments are still on the wall behind the Supreme Court Justices when they take the bench. Our coins still display the motto "In God We Trust." The US is still firmly part of a Western Civilization fashioned by a Judeo-Christian religious ethic and heritage. Alexis de Tocqueville observed more than a century and a half ago, "There is no country in the world, where the Christian religion retains a greater influence over the souls of men than in America." That is still true today. We live, not under a Christian government, but in a nation where all are free to practice their particular religion, in accommodation with other religions, and in accordance with the basic principles of the nation, which are Christian in origin. It is in that sense that America may properly be referred to as a Christian nation."

*I realise this figure is debatable.
The article is from 2001, and if anything has changed or is simply plain wrong in the above conclusion of the article then I apologise, and please let me know what these changes/inaccuracies are...
), that would say that the country overwhelmingly believed in God. That doesn't necessarily mean the God of the Bible. You are going on the assumption that America is a Christian nation before the poll was given. Isn't that circular reasoning? I've lived here all of my life, and I know for a fact that 90 % of Americans are NOT born-again Christians. If you really believe that, then you need to revisit to see for yourself.
