I've seen a lot of "fuck Arizona" posts but I wanted to add my two cents. I think that Joe Biden's (probable) win there is an anomaly that only happened due to COVID. Remember, Obama won Indiana in 2008 but other than that it's been Republican for decades. I won't get into Indiana right now but in 2008 the stars aligned for Obama. I don't think our performance in AZ is due to Californication, or at least that's only part of the answer.

Trump was definitely underperforming with seniors compared to 2016. A lot of that was due to MSM lies about Trump's handling of COVID, and unfortunately a lot (not all) of seniors don't know how to use the internet, or if they do they don't have knowledge of sites like TheDonald.win so they can see the truth. A lot of them haven't ditched cable yet. You also have to remember that seniors a lot of times vote in person, but COVID definitely might have scared some of them off (because they are actually the group that's truly vulnerable to COVID)

Trump did better in 2020 with the Hispanic vote (about 10%) but that was mainly in Florida and probably not the same Hispanic population in Arizona. He probably did better in AZ with Hispanics too but seniors vote at much higher rates and AZ has a lot of seniors.

Edit: Another reason might be that there was no love lost between McCain and Trump. Not sure how popular McCain was, or is, in Arizona but I'd imagine he got elected as a neocon war hawk in Arizona for a reason.

BTW: Do we really want to become a salt mine? Arizonans, New Yorkers, and even Californians are all our fellow Americans. We have a responsibility to redpill them too. Cubans who escape from communism come here and vote Republican because they know what the democrats will bring: socialism. So I see no reason why Californians who escape from Newsom can't be similarly convinced. The same thing goes for the black vote or any other group.
