Teamsters President James Hoffa pulled out of a campaign debate to fight it, but that didn't stop Oklahoma voters from approving a "right to work" law.

According to published reports, Oklahoma is the first state in 15 years to pass such a law, a constitutional amendment prohibiting mandatory union dues.
Hoffa last week pulled out of a scheduled debate with Tom Leedham, who is challenging him for the presidency of the union, in order to spend more time in Oklahoma. Spending by both sides in the campaign totaled more than $10 million. In the end, the proposal received 446,936 votes in favor, 378,236 against.
The decision makes Oklahoma the 22nd state to enact such a law. Right-to-work proponents hope the victory will help their efforts to pass similar laws in Colorado, Kentucky, Indiana, New Hampshire, New Mexico and Montana.
