It depends on who you ask and what year it is. Honestly, if you’re looking for a simple "yes" or "no" to the question, is Arizona a Republican state, you’re going to be disappointed. Arizona is complicated. It’s messy. It’s the kind of place where a voter might show up to a rally in a MAGA hat but then turn around and vote for a Democrat for the U.S. Senate.
For decades, the answer was an easy yes. This was the land of Barry Goldwater and John McCain. It was deep red, sun-baked, and reliably conservative. But walk through a suburb in Gilbert or a tech hub in Chandler today, and you’ll see a different reality. The "Red Wall" has some serious cracks in it.
The Identity Crisis of the 2020s
Let’s look at the scoreboard because the numbers tell a story of a state that’s basically split right down the middle. As of early 2026, Arizona has a Democratic Governor, Katie Hobbs, and two Democratic U.S. Senators, Mark Kelly and Ruben Gallego.
Wait. If the top of the ticket is blue, why do people still think of it as a GOP stronghold?
Because the Arizona State Legislature is still controlled by Republicans. They hold a 17-13 lead in the Senate and a 33-27 edge in the House. It’s a divided government in the truest sense. You have a Democratic executive branch constantly clashing with a Republican-controlled legislature over everything from school vouchers to water rights.
Then came the 2024 election. It flipped the script again. Donald Trump won the state by about 5 points, a significant jump from his narrow loss in 2020. Yet, at the same time, Democrat Ruben Gallego defeated Kari Lake for the open Senate seat.

Arizonans love to split their tickets. They might want a Republican president to handle the border but a Democrat in the Senate to protect social programs. It makes the state a nightmare for pollsters.
Is Arizona a Republican State by the Numbers?
If we look at voter registration, the GOP still has the upper hand. According to the Arizona Secretary of State’s data from late 2025, about 35.6% of voters are registered Republicans. Democrats trail at roughly 28.2%.
But here is the kicker.
The biggest group after the Republicans isn't the Democrats. It’s the "others." Around 34% of voters are registered as Independent or unaffiliated. These are the people who actually decide the elections. They don't care about party loyalty. They care about the cost of housing in Phoenix and whether there will be enough water in the tap twenty years from now.
Geography is Destiny (Sorta)
The political divide is literally written on the map:
- Maricopa County: This is the big one. It houses about 60% of the state's population. It used to be the crown jewel of the GOP, but it’s now the ultimate battleground. If you win Maricopa, you usually win the state.
- Pima County: Home to Tucson. It’s reliably blue, academic, and progressive.
- The Rural Counties: Places like Mohave, Yavapai, and Pinal are deep, deep red. In Mohave County, Trump pulled over 77% of the vote in 2024.
Why the "Red State" Label is Fading
There are three big reasons why Arizona isn't the Republican fortress it used to be.
First, the California exodus. People are moving to the Valley of the Sun for jobs in the "Silicon Desert." Companies like TSMC and Intel are pouring billions into the state. These new residents often bring more liberal or moderate leaning views with them.
Second, the Latino vote. About one in four Arizona voters is Latino. While Republicans have made some gains here—especially with men—the majority still leans toward Democratic candidates. However, it's not a monolith. Latino voters in Yuma have very different priorities than those in Maryvale.
Third, the MAGA vs. Establishment rift. The Arizona GOP has been through some internal warfare. The "McCain Republicans"—moderates and suburbanites—have often felt alienated by the more populist, Trump-aligned wing of the party. When these two groups fight, Democrats like Mark Kelly slip through the middle.
What Most People Get Wrong
People often assume Arizona is "turning blue." That's not quite right. It’s more like it's turning purple.
In 2025, the state dealt with massive debates over abortion rights after the 1864 territorial law resurfaced. That issue drove huge Democratic turnout. But at the same time, concerns over inflation and border security have kept the Republican base energized and won over many independents.

Is Arizona a Republican state? No. Is it a Democratic state? Also no. It is a battleground state where every single vote feels like it's being fought over with a megaphone.
The Road to 2026 and Beyond
We are currently looking at the 2026 midterms, and the stakes are ridiculous. Governor Katie Hobbs will be up for re-election. The entire state legislature is on the ballot. National Democrats have already pledged $50 million to try and flip those state chambers.
If you are trying to understand where the state is headed, watch these three things:
- The "Independent" Surge: Watch if more young voters continue to reject party labels entirely.
- The Housing Crisis: Phoenix has seen some of the highest rent increases in the country. Whichever party offers a real solution to "can I afford a house?" will win the suburbs.
- Water Management: This is the existential threat. If the GOP or Democrats can claim the mantle of "protecting our water," they’ll have a lock on the rural and suburban vote alike.
Actionable Insight for Observers:
If you're looking to gauge Arizona's lean, don't look at presidential polls. Look at school board elections and county supervisor races in Maricopa County. These "down-ballot" races are the true canary in the coal mine for which way the suburban wind is blowing. If the GOP starts winning back the school boards in Gilbert and Scottsdale, the state is shifting back toward the right. If those stay in moderate or liberal hands, the "Purple Arizona" era is here to stay.
