Assuming your synopsis is accurate, then it wouldn't matter. They should seek some representation from any administration, and lobby for address of their issues. Didn't have to be the convict. In fact, I suspect they'll get less motion from the convict than they would have from Harris. If the convict could deport them, he probably would.

I do agree they need to stop passively waiting. But, again, that would apply to any administration in power. Not convict-specific. And, while it is a bit more complicated than I'm about to say, they are semi-autonomous nations. They have their own government, their own police force, etc. That government should be addressing their problems as a first measure, and lobbying DC when appropriate. BIA has a somewhat mixed track record, but they can apply pressure to any administration just as a state governor could (more or less).

I was mildly curious, and googled-up a native woman (with position in the Navajo nation) giving her reasons for support. They amounted to "shared ideals", which was anti-abortion, and other conservative social issues (she didn't mention gay/trans, but I'm sure she's "anti", given what I read).
