I've been reading about the get out the vote effort of the Navajo and Hopi nations. If you recall, the Navajo have been very hard hit by Covid 19. When they asked for help with supplies the Trump Administration sent native tribes body bags.
For only the second time in the last 70 years, Arizona voters went for the Democratic candidate for president, and Navajo voters contributed to the swing.

Looking closely at the Arizona returns, it appears that it was the Navajo who put Biden over the top and helped flip Arizona.
The moral of the story is don't fuck with the Navajo.
