College presidents from about 100 of the nation's best-known universities, including Duke, Dartmouth and Ohio State, are calling on lawmakers to consider lowering the drinking age from 21 to 18, saying current laws actually encourage dangerous binge drinking on campus.

A story from the AP says, the movement called the Amethyst Initiative began quietly recruiting presidents more than a year ago to provoke national debate about the drinking age.

"This is a law that is routinely evaded," said John McCardell, former president of Middlebury College in Vermont who started the organization. "It is a law that the people at whom it is directed believe is unjust and unfair and discriminatory."

Other prominent schools in the group include Syracuse, Tufts, Colgate, Kenyon and Morehouse.

But even before the presidents begin the public phase of their efforts, which may include publishing newspaper ads in the coming weeks, they are already facing sharp criticism.

Mothers Against Drunk Driving says lowering the drinking age would lead to more fatal car crashes. It accuses the presidents of misrepresenting science and looking for an easy way out of an inconvenient problem. MADD officials are even urging parents to think carefully about the safety of colleges whose presidents have signed on.
