Check out this tight paragraph by Bill Moyers:

"What is unique today is that the radical religious right has succeeded in taking over one of America's great political parties - the country is not yet a theocracy but the Republican Party is - and they are driving American politics, using God as a battering ram on almost every issue: crime and punishment, foreign policy, health care, taxation, energy, regulation, social services and so on.

"What's also unique is the intensity, organization, and anger they have brought to the public square. Listen to their preachers, evangelists, and homegrown ayatollahs: Their viral intolerance - their loathing of other people's beliefs, of America's secular and liberal values, of an independent press, of the courts, of reason, science and the search for objective knowledge - has become an unprecedented sectarian crusade for state power. They use the language of faith to demonize political opponents, mislead and misinform voters, censor writers and artists, ostracize dissenters, and marginalize the poor. These are the foot soldiers in a political holy war financed by wealthy economic interests and guided by savvy partisan operatives who know that couching political ambition in religious rhetoric can ignite the passion of followers as ferociously as when Constantine painted the Sign of Christ (the "Christograph") on the shields of his soldiers and on the banners of his legions and routed his rivals in Rome. Never mind that the Emperor himself was never baptized into the faith; it served him well enough to make the God worshipped by Christians his most important ally and turn the Sign of Christ into the one imperial symbol most widely recognized and feared from east to west."
