Hi Bearheart:
To a small degree you may have misunderstood you friends. Citizens of Native States have a three part citizenship in the way you have a two part citizenship. They are full citizens of their states and federal government, however their Native Nation enjoys certain soveriegnty and immunities from certain state actions, such as the State can tax sales on Indian land, but has not power to collect that tax due to governmental soverign immunity. Now, some Native traditionals feel and to a degree international law agrees, that the Congress's granting itself plenary power over their origional soverienty is a violation of the rights of encapsulated and or conquored peoples (most of the US origional nations were not conquored by simply encorporated against their will by the growth of the new nation here). As such, they do not comply with some resitrictions on their origional rights. But all have the right to vote, though some do not choose to do so, standing on their belief that they should be wholely soverign. Forgive the spelling,
Larry
