That was a poll done at the beginning of this year and it showed that the rising debt was actually #2 on the minds of most Americans. It was ahead of such issues as taxes, healthcare, even gun control and this was right around Obama starting his big push for more gun control. In fact, it was just 1% shy of tying the economy in general. So yes, the debt is an issue on most Americans minds now. The problem is with politicians not willing to have an honest conversation and catering to both bases. We need cuts on spending and serious tax reform if we are every going to get things under control, and both those issues are currently not something that either party wants to do. Thus, we are at the impasse we are at.
When people's voting actually changes and we stop electing people based on sound bytes and how they look on TV, let me know. Polls can be made to say anything, based on how the questions are asked.
There is nothing demonstrably true that religion can provide the world that cannot be achieved more rationally through entirely secular means.
