>>But I always doubt the religious politicians. Their allegiance is double - to their religion and to their voters.
If you define them with conflicting interests, the comment is logical. But perhaps you also doubt all US politicians because their allegiance is double- to their Party and to their voters (but only enough to get voted in again.) Or perhaps that's only true of the crowd you don't vote for. In which case this is just another junk science argument to justify entrenched bias. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
