@mlurp,
That poll said that 86% of Americans believe that religious slogans should have a place in American government- it did NOT say that 86% of people polled believe in God. Those two issues really have nothing to do with eachother. I believe in God, but I don't believe in the combination of church and state. America was founded by people who were escaping religious persecution, and for this reason our laws include rights such as freedom of religion, freedom of speech, free exercise and the establishment clause.
In addition to the above political reasons, chuch and state should not be combined because no one should have to be exposed to a religion that is not their own. It is true that America has a large Christian population, but this is no reason to overlook the rights of non-Christians.
...And to answer your question about my belief in God- I don't just believe in God, I know Him. We speak daily- and He's a pretty great dude :]
