You can make a successful run for political office in this country without an especially thick résumé, any exceptional talent for expressing yourself, a noteworthy education or, for that matter, a basic grasp of science.But you better have religion. You better be ready to profess your faith in and fealty to God — the Judeo-Christian one, of course. And you better be convincing. A dust-up last week in the 2014 race for a United States Senate seat from Arkansas provided a sad reminder of this, showing once again that our ballyhooed separation of church and state is less canyon than itty-bitty crack.
