«According to an expert who testified in the RNC case, “approximately one-third of a [percent] of non-Hispanic White voters [in Arizona] are Federal-Only Voters, while a little more than two-thirds of a percent of minority voters are Federal-Only Voters.”

This racial disparity likely explains why the Republican Party is now asking the Supreme Court to further restrict this small percentage of Arizona voters. 2020 exit polls showed Republican Donald Trump winning white voters in Arizona, but losing the state as a whole due to President Joe Biden’s strong performance with Latinos. Biden’s margin of victory in Arizona in 2020 was about three-tenths of a percent, and even a tiny shift in the state’s population of eligible voters could tip the balance.»
