The right in America have the religious element; an element which Republican candidates are enthusiastic to court because it's so important. That seems not to be dead quite yet, but views on abortion, homosexuality and contraception which some have are clearly not as accepted as they once were.
Americans are still far more church-going than we are. Every politician mentions, somehere in their literature, not just which religion they belong to, but which sect, and often which place of worship too. Here, mentioning God is a political taboo ( "We don't do God" as Tony Blair said)
Jews are in established groups or sects; Orthodox, Liberal, Reform; just as Christians are , some are ultra-Orthodox too. There are some Jews who have bacon for breakfast, but they still regard themselves as Jews and Jewish.
All major religions shoot themselves in the foot sometimes. Not everyone is mainstream or in touch with the wider community, but it would be shame if the world took them as representative of the whole religion. Some Jews,I recall, quite seriously wanted to build a high fence around some streets in North London, because of some instructions in the Old Testament about surrounding a settlement. You can imagine how that was regarded by the wider world.
