MADISON, WI (WTAQ) - Indian leaders waged an aggressive campaign to get their members out to the polls on Tuesday – and their national group calls the effort a success.

It will be awhile before we learn how many Native Americans voted in Wisconsin and elsewhere. But the National Congress of American Indians said the tribal turnouts made a difference in Minnesota, where a referendum was defeated on a photo ID requirement for voting.

The group also said it had a hand in the U.S. Senate races in North Dakota and Montana.

Congress officials say Native Americans in New Mexico and Montana were registered at higher rates than any other racial or ethnic group going into Election Day.
