Unless you’re referring to the Arizona constitution, “The Constitution” applies to the federal government. Not the states.
But the federal constitution lays out when the Electoral College meets and when presidential terms begin and end. Say Arizona decertifies its slate of electoral voters? Then what? Are you expecting the electoral college to meet again and vote? Nothing in the Constitution allows for that. Are you saying votes cast in in December 2020 suddenly are withdrawn? Nothing in the Constitution or law allows for that. So even if they were decertified, which they won't be, what changes?
