The only Indians considered United States citizens “by birth” under the U.S.  Constitution were those not born into tribal membership or whose tribe no longer existed as a distinct legal entity such as “extinguished” tribes of Indians. The Puritans had officially exterminated the Pequots by the 1600’s, and taken their lands, but the Pequot survivors who were overlooked in the massacre were found and “resurrected” in the 1980’s by a Congressional act for the purposes of federal recognition of the “Pequot Tribe” to build an Indian casino on the Pequot reservation in the State of Connecticut, with a 25% revenue share for the state. Connecticut needed funds to cover millions of dollars of state budget shortfalls. The state requested an increased share of profits to cover state budget needs in order to avoid welfare cuts. It seemed tribal sovereignty and federal recognition could be enforced in Congress if the right senators could be reached.

 The State of Montana had originally used these laws to exclude Indians from voting, but the State “emancipated” competent Indians from tribal sovereignty to state citizenship by the Indian Bureau issuing illegal fee “patents” to Indian allottees who owned valuable lands they desired. Montana “Jim Crow” laws were enacted by the Montana Legislature that began in 1906 when the Montana Attorney General issued an opinion that Indian reservations should not be included in a voting district and that Indian wards of the government were not entitled to vote on the reservation or in state elections.
