re: #172 Nimed
All of this is speculation, of course. You are right that, since candidates are required to make those gestures, they are of practically no value to determine their true beliefs. I believe both Clinton and Obama (specially Obama) had a life experience more conducive to an atheist, or at least agnostic, view of the world than the Bushes. But who knows?
What life experience is conducive to being an atheist?
