AZ is iffy. The Maricopa Country Recorder has control of the ballots in Maricopa County, where a majority of voters are. However Maricopa County goes, so goes the state.
The guy was elected in 2016, sponsored by OurRevolution. His ballot harvesting (illegal in AZ), along with the ballot harvesting in Pima County (two Dem strongholds), will illegally give AZ to Biden, while electing even more House seats to the Dems.
