I see the problem. Here's the map of LD 26:

Tempe is ASU, a College Town. The really large part in the Northeast is the Fort McDowell Indian Res (leftist). Most of the part that's Mesa is the "Latino" area, the oldest part of town. Bottom line: Not Happy Hunting Grounds for Republicans. There is a "nice" part of Mesa in the district, I hope that's where you live.
LD 25 is all dense tract development with homes around $500K. A lot of people who can afford (and tolerate) houses like that, heavy advantage GOP.
LD 12 is a lot like 25 in demographics for the most part in that part of Gilbert, Queen Creek (part of QC is in Pinal County) is still mostly farmland, but there's a lot of new growth there. Call QC a mixture of farmers and a bedroom community.
LD 16 surprises me a bit if it's heavy GOP, that's Apache Junction, again not part of Maricopa County. There are a lot of snowbird retirees living in mobile homes, so it's only a small surprise.
I don't know where 10 or 24 are. My old district is LD 17. They went for Hillary in 2016, part of why I was happy to vacate the premises when I did. Looks like Mesnard, the Republican got Senator, but we split the Representatives with the Rats.
