A year ago, few people outside the world of state legislatures had heard of the American Legislative Exchange Council, a four-decade-old organization run by right-wing activists and financed by business leaders. The group writes prototypes of state laws to promote corporate and conservative interests and spreads them from one state capital to another.

The council, known as ALEC, has since become better known, with news organizations alerting the public to the damage it has caused: voter ID laws that marginalize minorities and the elderly, antiunion bills that hurt the middle class and the dismantling of protective environmental regulations.
