Idaho Is Changing: Secretary of State Phil McGrane on Growth, Politics, and the Road Ahead

Idaho is growing faster than most people realize, and that growth is reshaping everything from the skyline to the statehouse. That was the central message from Idaho Secretary of State Phil McGrane, who addressed a room of business leaders and elected officials at the Elected Officials Outlook Series on June 3, 2026, at The Grove Hotel in Boise.
​
Drawing on voter registration data, business filing records, and demographic trend analysis from his office, McGrane offered a data-driven look at who is moving to Idaho, how they are participating in the political process, and what it means for the state going forward.
​
A State in the Middle of a Shift
McGrane opened with a simple observation: Idaho is not the same state it was even a decade ago, and the rate of change is accelerating. Business filings in the Secretary of State's office have grown from roughly 425,000 in 2020 to more than 650,000 last year, representing a 50 percent increase in just five years. The Boise skyline itself reflects that transformation.

McGrane emphasized, is not only physical. It is demographic and political.

Who Is Moving Here, and Why It Matters
McGrane's office tracks the last known address of every new voter registration in Idaho, a data point collected for the practical purpose of notifying other states to remove voters from their rolls. But his data visualization specialist saw a broader story in the numbers.

Currently, 127,000 Idahoans whose last known address was out of state are registered to vote here. Of the 49 other states represented, the majority of those new voters are registered Republicans. The largest group by far comes from California, with 77 percent of California transplants registered as Republicans. McGrane pushed back on the common assumption that migration from California means a liberal shift.

"It is not blue haired hippies from the Bay area," he said. "What you're seeing is tons of people packing up and moving to be in a place with different values, different quality of life." Many are what McGrane called political refugees, motivated to leave their home states precisely because of changes in governance, and that motivation, he noted, tends to translate into high civic participation.

The trend is bearing out in registration numbers. When McGrane took office, 58 percent of Idaho's registered voters were Republicans. Today that figure stands at 62 percent, with only 12 percent registered as Democrats and roughly twice that number unaffiliated.

The Primary Determines the Direction
One of the most striking visualizations McGrane shared illustrated how few Idahoans are actually deciding the direction of state policy. Of 1.4 million eligible voters, 73 percent are registered to vote. Of those, only about half are registered with a political party. And of those, just 22 percent turned out for the May 19 primary.

"In terms of what are the demographics of the people deciding the future of the state," McGrane said, "this is a big factor."

He used the example of a 2020 Highway District Commission race decided by two votes out of 40,000 cast, a race in which 10,000 voters had a ballot in hand and chose not to fill in that contest. The point was not simply that elections are close. It was that the people making consequential decisions about infrastructure, development, and policy are a small and aging slice of the eligible electorate.

McGrane also noted that while November elections draw far higher turnout, the primary is where most of the consequential decisions are already made. He urged business leaders in the room to recognize that engagement before November matters as much as engagement on Election Day.

Competing Visions Within a Dominant Party
McGrane spent time on the internal dynamics of the Idaho Republican Party, which he described not as monolithic but as increasingly defined by regional and generational tension. People who have lived in Idaho for generations bring different priorities than those who arrived in the last few years from dense urban areas, even if both groups voted for the same presidential candidate.

He cited the 2024 legislative session as an illustration, when the hottest debate was over library book placement while water calls were being issued in eastern Idaho. "Those water users' priority was not library books, it was water," he said. "That is a summary of just the different priorities and the different regions of the state."

He closed the formal portion of his remarks by reading from a post-election analysis piece that framed the challenge in stark terms: Idaho's future will depend on whether its competing visions of conservatism can learn not merely to coexist but to govern together.

Ballot Initiatives and What Comes in November
Responding to a question about upcoming ballot initiatives, McGrane confirmed that a reproductive rights measure is on track to qualify for the November ballot based on signature submissions throughout the year. A medical cannabis measure is also in the verification process, with the June 30 deadline for signature review meaning Idahoans will know by early July what will appear on the ballot.

McGrane said both issues will draw significant outside money and could drive participation, but cautioned against assuming November will be an unusually high-energy cycle. Primary turnout of 30 percent, he noted, was already strong by historical standards. He observed that increasingly, national dynamics shape local outcomes more than local factors alone, a shift he sees reflected in the volume and source of campaign spending flowing into Idaho races.

Where Idaho Goes From Here
When asked whether newly arrived Idahoans might moderate over time, McGrane was measured but clear that backward-looking nostalgia is not a useful lens. "We're not going backwards," he said. "We get to determine where that direction is and where the course of the state goes."

He pointed to the tension between large and small business interests, between rural and urban priorities, and between Idaho's longstanding identity and the values of those who have chosen it as a destination as defining challenges for the years ahead. The state is not going to stop growing. What it does with that growth is still an open question.
