I don’t know much about AZ’s internal politics, but how can 70% support this legislation and 47% support open-borders, anti-fence John McCain [of McCain-Kennedy; aka, Amnesty for Illegals] for re-election?
Because some Arizona people truly believe McCain’s campaign talk. Many in Arizona really want to believe McCain is their hero. At least that was the case when I lived in AZ during the McCain/Keating issue. Some just don’t want to believe anything bad about him, no matter how much proof is in front of them.
I think that has been because even liberal Dems will vote for Maverick Juan (Media, AZ) because they have no Democrat to support. IIRC, he ran unopposed on the (D) side last time.
But even these (D) voters do not like the effects of illegal immigration in the state, and did not support Juan's last attempt at “shamnesty”...
