So, I have to say that of all the polls I've seen, the ones I distrust the most are ones that have Trump winning bigly in Arizona. This is anecdotal, and I live in a slightly bluer than average area in the state, but this is the first time I've lived in the same place for two election cycles since I've been eligible to vote, so this is the first time I can actually make a comparison.
I think that enthusiasm for Trump is way down in comparison to 2020. I'm seeing a lot fewer yard signs up for Trump, and I've not seen a single one of the dumb fucking MAGA caravans that were ubiquitous in 2020. Combine that with prop 139 being on the ballot, and the fact that Lake is getting crushed in the polls by Gallego, I think that Harris will massively outperform her poll numbers here. If it were still Biden running then maybe I could see a lot of people splitting the ticket and voting Trump, Gallego, and yes on 139, but Harris actually has a net-positive favorability rating (unlike Trump), so I definitely don't see Harris losing here by the margins some polls are suggesting. She might still lose here, but I'll be very surprised if it's not close.
