Great suggestion...start here:  The Indian Citizenship Act of 1924 made all common Indianlaw-federal and state-including Commerce and Treaty Clauses (if the U.S. Senate did approve treaties of any prior to 1878) moot.  That is, all references to "Indians" in the Constitution vanished!  Why? The Constitution makes for no provisions to regulate the metes and boundaries of a U.S./State citizen because of their ancestry/race including the newly minted U.S./State citizens with "Indian ancestry/race."  And, the Constitution makes for no provisions for 'treaties' with its own constituency.  The Constitution makes for no provisions for "sovereign Indian nations!"  Everything being noted by politicians and Wikipedia about U.S./State citizens with "Indian ancestry/race" pre-Citizenship is merely history. And, all common law-federal and state-naming a U.S./State citizen with "Indian ancestry/race" for regulation post 1924 Citizenship has no Constitutional authority to exist.  My question remains.
